18 Great Cardio Workouts That Don't Require Running

Old school moves meet forward-thinking exercise routines at Throwback Fitness in New York interval workouts, you can reap even more cardio benefits than you would on a treadmill, says co-owner Ryan Wilke. Try repeating this short circuit of bodyweight exercises — completing as many rounds as you can in four minutes — followed by jumping rope as many times as possible in one minute. Repeat for a total of five circuits.

Workout:

• 10 squats: Stand with feet hip-width apart and squat down as low as you can, keeping shoulders up and back flat. Press through heels to stand.
• 10 pull-ups: Start from a dead hang and pull yourself fully up to the bar, so it’s level with your collarbone.
• 10 push-ups: Keep the elbows snug to the body as you lower your chest to the ground and then raise back up.
• After completing as many rounds of squats, pull-ups, and push-ups as possible in four minutes, jump rope for one minute, then complete the circuit four more times.

The next time you find yourself at the ocean, head to the nearest net. "Moving around quickly on sand takes a lot more energy than moving fast on something hard like cement," says Scott Herman, a trainer with the BeFit Network. "The sand shifts under your feet, which means you're constantly correcting yourself and having to generate a ton of power, especially when jumping high." The unstable sand is also great for strengthening legs and ankles, which tend to weaken as you get older. Plus, unlike a grueling 45 minutes of running on a treadmill, volleyball is usually done with friends, so you can go for hours without noticing it.

If you love the long and isolated nature of running, hop on two wheels instead. "Cycling is great because you can change your intensity depending on the terrain you choose," says Herman. "You can go mountain biking, which is more intense and requires bursts or speed, or road cycling, which tends to be more endurance based." If you do go out, make sure you use clip-ons so you work your hamstrings as much as your quads. And plan your route ahead of time. That way if you'll know when a downhill is coming up and push yourself as hard as you can leading up to it.

The whole point of high intensity interval training is to push yourself so hard that your heart rate goes sky high instantly. Just try a few tabata rounds and see if you don't notice a faster pulse. "With tabata, you go at maximum effort for 20 seconds, rest for 10 seconds, and do eight cycles," says Iwaniuk. "The key is pushing yourself hard in those 20 seconds. If you're willing to put yourself through the ringer, your heart is going to be pumping a ton of blood through it and you'll stay in the zone of an elevated heart rate the whole time, even during the rests." A good goal: Try not to slack off as the rounds go on — if you did 18 air squats in round one, get 18 in round eight.

Just try hitting a heavy bag for a few minutes and you'll quickly see why boxing counts as cardio. "With boxing, you're constantly shuffling, twisting, keeping your arms up at a high level, and using a lot of speed and coordination to punch," says Iwaniuk, who thinks this, as well as activities like judo and jiu jitsu, are the pinnacle of non-running cardio training. "Any time you repeatedly strike something for a set amount of time, you will work your heart big time." If you're at home without a heavy bag to take it out on, pick up some light weights and shadow box. "It's tough to throw 200 punches with any kind of weight in your hand," says Iwaniuk. "Even two pounders!"

Jumping jacks don't require any equipment, you can do them anywhere, and they are so simple they do them in elementary school gyms. "Do them the standard way — arms going overhead — or cross your arms over your chest to improve shoulder flexibility," says Corkill "It gets the upper body involved as well as lower, whereas something like cycling only uses your leg muscles." Corkill likes to add quick bursts of jumping jacks throughout a workout to spike your heart rate.

"You end up using every bit of energy you have to get from point A to point B when you're swimming," says Herman. "You also kind of trick your brain because you're tiring out your body, but the water makes it tough to feel sweaty. Plus the pool keeps your core temperature down, which means you might be able to last longer." His suggestion is to alternate laps of easy paces and sprint paces to get your heart rate up while allowing you to stick it out in the pool.

This isn't the best form of cardio for someone just starting out — it's way too easy to get sloppy and have bad form — but if you're already pretty fit, burpees will get your heart rate up in no time. "These use absolutely everything," says Corkill. "That's why they're so efficient—they tax a lot of muscles at once, especially if you add a push-up at the bottom."

Pump the treadmill up as high as it can go — some get all the way to 30 degrees — and start walking on it to get your heart rate soaring instantly. "It pushes your legs and lungs without the pounding of running," says Corkill. "That means this is a great form of cardio if you need to save your knees or hips." Don't hold on to the side bars and when you start to get tired, make sure you don't slouch over. Start out at a 3.2 to 4.0 speed, which will be plenty, and see if you can make it 15 minutes.

This routine from Wilke and Gallagher combines jump rope, dumbbells, and bodyweight exercises. Perform five rounds, trying to beat your best time. If you stop or catch your feet while jumping rope, you must complete three burpees before resuming the workout.

Workout:

• 10 dumbbell push presses: With the dumbbells in front of your shoulders, bend at the knee by a few degrees to drop your hips straight down. In one strong motion, extend the knees and hips and let the momentum travel into the dumbbells to press them overhead.
• 20 push-ups: Keep the elbows snug to the body as you lower your chest to the ground and then raise back up.
• 30 crunches: Laying on your back, curl your trunk so you're raising your shoulder blades off the ground.
• 40 lunges: Keep your front knee over your ankle and tap back knee to the ground, practicing balance and control throughout the movement.
• 50 unbroken jump rope turns.

Want a bigger challenge than dumbbells or kettlebells? Wilke and Gallagher of Throwback Fitness change up their routines by incorporating medicine balls into their workouts. Try completing 10 rounds of the following circuit as fast as possible.

Workout:

• 10 overhead lunges: Hold the med ball overhead. Perform five reps on each leg.
• 15 thrusters: Holding a med ball at the top of your chest, drop down into a squat, then explode upwards, pushing the ball toward the ceiling.
• 20 medicine ball sit-ups: Hold the ball against your chest for the sit-up.

Make your next strength workout more challenging by grabbing a pair of heavy dumbbells, says Gallagher. By performing this extra effort without slowing down, you'll turn a weight-lifting session into a weight-plus-cardio one. Set a 24-minute timer and complete as many levels of the following increasing ladder as possible. Every three minutes, stop where you are and complete five burpees. Follow the same pattern, increasing your reps by two for each round. For example:

Workout:

• Round 1: 2 renegade rows, 2 thrusters, 2 weighted lunges, 2 weighted sit-ups
• Round 2: 4 renegade rows, 4 thrusters, 4 weighted lunges, 4 weighted sit-ups
• Round 3:6 renegade rows, 6 thrusters, 6 weighted lunges, 6 weighted sit-ups

Renegade rows: Grab a pair of dumbbells and start in a plank position with both hands gripping the weights. Your body should form a straight line from your head to your heels and your feet should be a little more than shoulder-width apart. Keeping your hips still, pull your right elbow up into a row, then return the dumbbell to the floor. Repeat this movement with your left arm for one rep.

Thrusters: Holding a pair of weights at your shoulders, drop down into a squat, then push through your heels to explode upward, pushing the dumbbells toward the ceiling.

Weighted lunges: Keep your front knee over your ankle and tap back knee to the ground. Hold the dumbbells by your waist, or for added difficulty, overhead.

Weighted sit-ups: hold one dumbbell by both ends, across your chest. For added difficulty, press the dumbbell over your head at the top of the sit-up.

Who needs a treadmill? With this workout, from Wilke and Gallagher, all you need is your body, a little floor space, a towel to mop up with. The key: Don't take a break. Go as hard as you can in 15 minutes, completing the maximum rounds possible.

Workout:

Kettlebell workouts are a mix of strength training and cardio, says Tina Tang, a StrongFirst-certified kettlebell instructor and personal trainer. "It takes a lot of effort to perform weighted lifts, and by doing the exercises without stopping, you'll also crank up your heart rate." Tang recommends starting with a kettlebell that weighs 35 to 44 pounds (16 to 20kg). Complete as many rounds as possible within 15 minutes.

Workout:

• 10 kettlebell swings: Start in a deadlift position, grasping the handle with both hands. Then, thrust your hips forward, letting the kettlebell extend naturally until it's in front of your chest. Keep your elbows locked through the movement and lower the weight back to the starting position. If you're already comfortable with kettlebell swings, extend the swing to overhead.
• 10 kettlebell squats: Grip the handle of the kettlebell with both hands, holding the weight to your chest. Keeping your feet slightly wider than shoulder-width part and your back straight, drop down as low as possible, then push up through your heels to the starting position.
• 10 kettlebell overhead press: Hold a kettlebell in your right hand, with the weight resting on the back of your wrist, tucked in front of your shoulder. Extend your arm toward the ceiling, pushing the weight over your head. Return to the starting position. Perform five reps with each arm.

Rowing is a blend of cardio and strength training, but it's low impact, so it's easier on your knees than running, says Scott Marchfeld, a trainer at Row House studio in New York City. Follow this rowing pyramid twice as you ratchet up, and dial down, your cadence.

Warm Up: Start with a five-minute light row at 20–22 strokes per minute.

Workout:

• Row hard, but not all out, for 30 seconds, maintaining a stroke rate of 24 strokes per minute. You'll be raising and lower your pace over seven segments, and the pyramid looks like: 24-26-28-30-28-26-24.
• After 30 seconds, increase the stroke rating to 26 strokes per minute while maintaining the same power output (watts) per stroke. Hold the pace for 30 seconds. Your average split should drop at least five seconds with each jump in pace.
• Continue raising the pace by two strokes per minute every 30 seconds until you hit 30.
• After rowing at 30 strokes per minute, bring the stroke rating back down to 28 per minute for 30 seconds. Be careful not to increase your split time as you slow down the rating.
• Continue bringing down the rating, every 30 seconds, until you're back to 24 strokes per minute.
• After your last 30 seconds, do a one-minute recovery row and repeat the pyramid workout one more time. Afterwards, do a one-minute cool down, then stretch.

High-intensity interval training (HIIT) workouts are short in time, but high in intensity. By going all-out and challenging yourself to perform the exercises in the shortest amount of time possible, you're guaranteed to get your heart rate pumping, says Grigas.
Perform each of the movements below using a three-round, 21-15-9 rep count. For example, you'll do 21 jumping lunges, followed by 21 push-ups, then perform 15 jumping lunges and push-ups, then a round at nine reps.

Jumping lunges: From a standing position, jump into a lunge, with your right knee bent at a 90-degree angle. Then, push up through your heel and switch sides in the air, so your left leg is bent at a 90-degree angle. That's one rep.
Push-ups: Keep the elbows snug to the body as you lower your chest to the ground and then raise back up.

Talk to any swimmer, and they'll insist that their workouts are harder than any other athlete's. They're probably right: Swimming laps for just 30 minutes can burn 400 calories. Plus, you're working just about every muscle in your body, says Jamie Grigas, a coach at EVF Performance in New York City. This workout was designed for a 25-yard pool (each lap is equal to 25 yards).

Warm Up: 300 yards freestyle, 100 yards kick (use a kickboard or perform a side kick), 200 yards freestyle, 50 yards kick.

Workout: Do 25 yards of kicking, followed by 50 yards of freestyle swimming, followed by 25 yards of kicking. Repeat 10 times, then swim an easy 50 yards to recover. Perform ten 25-yard pool lengths without breathing. Take as much time as you need to between 25-yard laps. (If you are not making the whole 25 yards, just try to make it longer than the previous one.)

Cool down: Perform a low-intensity backstroke for 100 yards.

One of the best ways to push your workout to a fat-burning cardio level is to grab a friend. "Exercising with a partner motivates you to work harder because you don't want to let your teammate down," says Wilke, which is why at Throwback Fitness, he and Gallagher pair up clients who attend their classes. Have one partner use a rowing machine, while the other performs exercises on the floor.

Workout:

• Person 1: Row at a hard, but sustainable pace
• Person 2: Perform 10 hand release push-ups, followed by 15 kettlebell swings
  Switch when the second partner completes two rounds; continue for 16 minutes (or desired workout length), keeping track of the total distance each person has rowed.
