Beyond the Treadmill: 5 Fun Ways to Build Cardio Without Boredom
Lynne Steiner • February 3, 2025
Tired of the Dreadmill? Let’s Fix That
Let’s be real—running in place while staring at a gym wall is about as exciting as watching paint dry. If you’ve ever found yourself glancing at the clock every 30 seconds on the treadmill, wondering if time has actually stopped, you’re not alone.
The good news? Cardio doesn’t have to feel like a punishment. You can build endurance, torch calories, and improve your fitness without subjecting yourself to the soul-crushing monotony of a treadmill.
Here are five fun, effective ways to get your heart pumping—no hamster wheel required.
1. Sled Pushes: Cardio That Feels Like a Power Move
If you want to feel like an absolute beast and build killer endurance, grab a sled and push it. This is the type of cardio that doesn’t just make you sweat—it makes you feel like a warrior charging into battle.
Why It Works:
Full-body engagement
– Your legs, core, and arms are all working hard.
Low impact, high intensity
– Unlike running, sled pushes don’t pound your joints.
Mental toughness
– You vs. the sled. It’s a battle every time.
How to Do It:
Load a sled with a moderate weight (enough to challenge you but not turn your legs into cement).
Grip the handles, lean slightly forward, and drive through your legs.
Push it 60-90 feet, rest, and repeat for 4-6 rounds.
💡 Want a real challenge? Add a pull-back sprint after each push to spike your heart rate even more.
2. Jump Rope: Old-School Fun, Next-Level Cardio
Remember jumping rope as a kid? Turns out, it wasn’t just playground fun—it was sneaky cardio conditioning. Now, it’s time to bring it back, but this time, you’re not just trying to avoid tripping over your feet.
Why It Works:
Skyrockets heart rate
– Just 60 seconds can leave you breathless.
Improves coordination
– Great for balance, agility, and rhythm.
Portable & efficient
– You can do it anywhere.
How to Do It:
Grab a rope and start with simple single jumps.
Once comfortable, mix it up with double-unders, side swings, or crisscrosses.
Try a 5-minute EMOM
(Every Minute On the Minute):
30 seconds jump rope
30 seconds rest
Repeat for 5 rounds
💡 Feeling spicy? Try a Tabata—20 seconds fast jumps, 10 seconds rest, for 8 rounds. It’ll humble you quickly.
3. Rowing: Cardio That Builds Muscle Too
If running is like a bad first date—awkward, exhausting, and never-ending—rowing is like discovering your soulmate. It’s a full-body burn that doesn’t wreck your knees but still leaves you gasping for air.
Why It Works:
Total-body workout
– Unlike running, rowing engages your legs, back, and arms.
Low impact, high intensity
– Perfect for those avoiding joint pain.
Strength + endurance
– Builds power while improving cardiovascular fitness.
How to Do It:
Set up the rower with a moderate damper setting (somewhere between 4-6 is ideal for most people).
Focus on a strong drive with your legs, then pull with your arms.
Try this rowing interval workout:
250m row, rest 1 min
500m row, rest 1:30
750m row, rest 2 min
500m row, rest 1:30
250m row
💡 Turn it into a race with a friend. Nothing makes you push harder than a little competition.
4. Assault Bike Sprints: The Love-Hate Relationship You Need
The Assault Bike, also known as the Devil’s Tricycle, is proof that cardio can be both incredibly effective and wildly humbling. A few seconds of all-out effort will make you question your life choices in the best way possible.
Why It Works:
Burns massive calories
– High output, short time.
Zero impact on joints
– Safe for anyone with knee or ankle issues.
Crushes endurance & strength
– It’s cardio that makes you stronger, too.
How to Do It:
Hop on the bike and get comfortable (as comfortable as one can be on this thing).
Try 15-second max effort sprints,
followed by 45-second slow pedals, for 10 rounds.
Or, for the truly brave:
30-second sprint
30-second rest
Repeat 10 times
💡 Want to level up? Pair it with push-ups or kettlebell swings in between rounds for a true full-body burner.
5. CrossFit-Style EMOMs: Small Work, Big Results
If you love the feeling of pushing hard but hate the thought of endless cardio, EMOMs (Every Minute On the Minute) are your secret weapon. They’re quick, effective, and keep your workouts fresh.
Why It Works:
Time-efficient
– Short bursts of effort maximize results.
Never boring
– Constant movement keeps you engaged.
Customizable for any level
– Scale the reps or movements based on your fitness.
How to Do It:
Pick 2-3 movements (bodyweight or weighted).
Set a timer for 10-15 minutes.
Every minute, perform the designated reps, then rest for the remainder of the minute.
🔥 Example 10-Minute EMOM:
Min 1: 10 kettlebell swings
Min 2: 10 box jumps
Min 3: 10 burpees
Repeat for 3-4 rounds
💡 Feeling ambitious? Add in a rowing or bike sprint for even more of a challenge.
Final Thoughts: Ditch the Dreadmill, Keep the Sweat
Cardio doesn’t have to be a monotonous grind on a treadmill. Whether you’re pushing sleds, jumping rope, or battling the Assault Bike, there are plenty of ways to build endurance without the boredom.

The holidays are full of celebration - family time, great food, and once-a-year traditions. They can also toss routines aside. The good news: you don’t have to choose between enjoying the season and feeling your best. With a few simple strategies, you can eat, drink, and be merry without feeling sluggish or off track in January. These are my go-to tips to help you stay balanced, energized, and fully present… because feeling good shouldn’t take a holiday. Savor Once-a-Year Favorites (Skip the Everyday Stuff) Seasonal treats are meant to be enjoyed. Spend your splurges on the dishes you truly love - Grandma’s pie, your aunt’s famous cookies - rather than store-bought snacks you can have any time. Slow down and actually taste the special stuff. One holiday dessert won’t derail progress. Pro tip: Don’t arrive starving. A light protein-and-fiber snack beforehand helps you choose intentionally and enjoy reasonable portions. Mingle and Make Memories (Not Just with the Buffet) Holiday gatherings are about people and moments. Fill your plate, then step away from the food table. Chat, play a game, take photos, or hang with the kids. If you need something in your hands, hold water, seltzer, or a small plate of veggies. Socializing away from the snacks reduces mindless nibbling and makes the night more meaningful. Load Up on Veggies and Protein First Aim for ½ plate veggies and ¼ plate protein (turkey, ham, tofu). Use the remaining space for the starchy sides or dessert you truly want. Veggies and protein increase fullness and make portion control easy while still leaving room for favorites. Hydrate and Sleep Like It Matters (Because It Does) Keep water nearby all day and between party drinks. Hydration supports energy and helps manage cravings. Prioritize 7–8 hours of sleep when you can - being well-rested steadies appetite, mood, and decision-making. If You Drink, Do It Smart (Mocktails Welcome) Set a limit and sip slowly. Alternate : one alcoholic drink, then water, seltzer, NA beer, or a mocktail. Choose lighter options : dry wine, light beer, or spirits with soda and citrus. Go festive without alcohol : zero-proof cocktails, NA beers, or spiced cider deliver the vibe without the hangover. Stick With Simple Structure (Most of the Time) Consistency on non-party days is the secret. Meal prep or plan basics : veggies, lean proteins, whole-food carbs. Keep easy options ready (pre-chopped veggies, yogurt, nuts). Consider help : locally, Meal Me; nationwide, Factor - prepped meals save time and keep you aligned with goals. Keep regular meal times : steady meals stabilize energy and reduce the “I’m starving” spiral. Keep Moving Some movement always beats none. Keep your routine, scaled to the season : if you usually train 4–5 days, two is still a win. Make it festive : family walk after dinner, holiday lights stroll, quick at-home yoga, a Turkey Trot, backyard games, dance while you bake. New here? Start small now : one class a week or a 15-minute walk daily builds a habit that feels effortless in January. Embrace Balance Perfection isn’t the goal - consistency is. Enjoy the foods you love, hydrate, sleep well, move your body, and return to your usual rhythm at the next meal. Focus on people and memories, not food rules. That’s how you finish the season happy and healthy. Want More Support?

When Krishna and I met for his goal review back in March, he was honest about where he was struggling. His last marathon had been a grind. Cardio-wise, he felt fine, but when it came to strength, he hit a wall. Fast forward to this fall, and the story looks very different. Krishna ran the New York City Marathon , one of the toughest, hilliest courses around. Not only did he finish strong - within 30 seconds of his Chicago time on a much harder route - but he recovered faster than ever. “Doing CrossFit often in the last few weeks helped me a lot,” he said. “The main difference was recovery. I flew back the next morning and wasn’t tired or exhausted.” That’s what consistency does. In September and October, Krishna committed to his CrossFit training, showing up with purpose and putting in the work to build the strength that had been missing from his marathon prep. He also made small, steady changes outside the gym - like sticking to a nutrition habit of no late-night eating after 7:30 PM. Simple, consistent actions that made a big difference in how he felt. Running long distances demands endurance. But running them well demands strength, stability, and recovery. Krishna’s story is proof that when you balance both, you don’t just survive the marathon - you thrive through it. 👏 Huge congratulations, Krishna! Your hard work is inspiring!
Move Better, Hurt Less: How Mobility Unlocks Strength and Longevity Picture this: you’re halfway through a set of back squats, the bar feels heavy—but not because your legs are weak. It’s because your hips refuse to cooperate. You’re grinding through molasses instead of moving like a well-oiled machine. That stiffness? It’s your body’s way of whispering (or maybe yelling): “Hey, we’ve got a mobility problem.” Most people treat mobility like the sad salad sitting next to the steak—important in theory, ignored in practice. But here’s the truth: mobility is strength in motion. It’s what allows your power to actually show up when it matters—on the barbell, on the field, or when you’re picking up your kid without feeling your lower back file a complaint. Mobility Isn’t Stretching—It’s Strength That Moves Stretching is what you do when you want to touch your toes. Mobility is what you need to pick up your keys without pulling a hamstring. Mobility is the marriage between flexibility and control. It’s your ability to move through a range of motion with strength and stability. It’s not about forcing yourself into yoga poses or chasing “looseness.” It’s about earning the right to move freely. Think of it like the difference between: - A floppy noodle (too flexible, no control) - A stiff board (too tight, can’t move) - And a panther—supple, powerful, and ready to pounce You want to be the panther. The Strength Ceiling: You’re Stronger Than You Think—If You Could Just Move Better Here’s the painful irony: most athletes aren’t limited by strength. They’re limited by how well they can move. Let’s say your hips are tighter than your jeans after Thanksgiving dinner. When you squat, your body compensates—knees cave in, heels lift, and suddenly that strong foundation feels like a Jenga tower in a windstorm. It’s not that your legs are weak; it’s that your joints don’t have room to do their job. Mobility dictates: - How deep you can squat (hips + ankles) - How well you can press overhead (shoulders + thoracic spine) - How powerfully you can jump, land, and change direction (everything working together) Without mobility, you’re driving a Ferrari with the parking brake on. The engine roars, but you’re not going anywhere fast—and something’s going to burn out. The Injury Loop: Tight Today, Hurt Tomorrow Every gym has that one person who’s “always working around something.” Maybe it’s a cranky shoulder. A hip that pops. A knee that protests like it’s on strike. Here’s the cycle: 1. You move with limited mobility. 2. Your body compensates. 3. You get away with it—for a while. 4. Then pain shows up, uninvited, like a bad sequel. Poor mobility is sneaky because it doesn’t scream right away. It whispers—until one day your shoulder taps out during kipping pull-ups or your lower back flares mid-deadlift. Mobility training interrupts that loop. It restores movement patterns before they spiral into dysfunction. It teaches your joints to work together instead of fight each other. And the cool part? You don’t need an hour of foam rolling or a full yoga session to make progress. Sometimes five intentional minutes a day can turn chaos into control. Mobility Is the Foundation for Longevity Let’s zoom out. Mobility isn’t just about performing better in workouts—it’s about living better, longer. It’s about bending down to tie your shoes at 70 without groaning like a haunted house door. When you move well: - Your joints stay lubricated and healthy. - You build resilience against falls, injuries, and daily wear. - You stay independent—because you can still squat, reach, twist, and play. Mobility keeps your movement currency high, so you can spend it however you like—whether that’s crushing “Fran,” chasing your grandkids, or hauling Costco groceries like a CrossFit Games event. The 5-Minute Rule: Small Effort, Massive Payoff Here’s your action step—and it’s ridiculously simple: 👉 Spend 5 minutes a day working on your tightest area. That’s it. No fancy tools, no hour-long routines, no “I’ll start next Monday.” Focus on one zone that gives you trouble—hips, shoulders, or ankles—and hit a few drills consistently. Example: - Hips: Couch stretch + 90/90 transitions - Shoulders: Banded pass-throughs + wall slides - Ankles: Weighted dorsiflexion rocks + heel drops Do it after class. While dinner’s in the oven. When you’re scrolling reels. Tiny, daily deposits lead to big returns. Because mobility doesn’t just add years to your training—it adds *quality* to those years. The kind that feels strong, fluid, and pain-free. Final Thought: Don’t Settle for Stiff You don’t need to live with tight hips, cranky shoulders, or knees that sound like bubble wrap. Mobility work is the unsung hero of progress. It’s the bridge between strength and freedom—the quiet discipline that keeps your engine running smoothly when everyone else is breaking down. So, next time you finish a workout, take five minutes to move with purpose. Not because you have to, but because your future self will thank you. Move better. Hurt less. Live more.
