Losing body fat is essential to obtaining and maintaining a lean physique.
Endurance exercise like running or biking outdoors for hours is super fun but at what cost does this come to hard earned gains?
Although there are some hybrid athletes that stay big, lean and have Ironman-like endurance, most bodybuilders do cardio for its cardiovascular and aesthetic benefits–not necessarily to compete in a triathlon.
Nonetheless, sometimes the same old “Stairmaster with a hoodie on” or “treadmill incline walk for hours” gets boring or straight up doesn’t work due to the body getting used to this type of stress.
Physique-minded athletes should incorporate various forms of cardio into their workout including high intensity interval training, steady state cardio and moderate yet challenging endurance sessions.
A weightlifter’s priority is to lift weights so we gave you a cheat sheet for sparking a new fire into your cardio routine. The first three workouts use two cardio machines and the last uses four all to provide a functional workout that burns maximum calories.
Incorporate one workout into your workout routine 1-2 times a week.
A heart rate monitor is one of the best and most practical ways to measure your effort levels, especially during running. Most endurance coaches will divide effort into five zones based on the maximum heart rate (MHR). To find your MHR, use the following equation: 208-0.7 x your age. That’s 208 minus 70% of your age. This equation has been shown to be more accurate than the 220-age equation.
The standard American College of Sports Medicine and National Strength & Conditioning Association recommended percentage of MHR range for developing aerobic fitness is 50-85%.
If you’re in this range, you’ll see improvements in VO2max (the maximum amount of oxygen you can consume during exercise) in addition to better circulation, decreased resting heart rate and lower submaximal exercise heart. A lower resting and submaximal heart rate is something you want–it means you do more work without as much effort. Of course the end result is there is more body fat loss.
Go above the 85% MHR like in some of these workouts, and you’re likely doing high intensity interval training (HIIT) workout where you intersperse work periods with equal, shorter or longer periods of rest.
If your work to rest ratio is 60 seconds to 60 seconds, you should see your heart rate decrease from 85%+ to 70-75% of MHR by the end of the recovery period. If you’re 15 minutes into a HIIT workout and your heart rate isn’t decreasing below 75% MHR, you need to increase the recovery period to 90-120 seconds.
Power through these four workouts to leave the gym more shredded and fit than ever.
Directions: Get on the Stairmaster and do the prescribed workout. Then, move on to the treadmill and do the prescribed workout. Wear a heart rate monitor and sync it to an app like Polar, MyZone, etc to track your intensity levels.
Total Workout Time: 35 minutes
Directions: Start the workout on a Cybex Arc Trainer, Octane Fitness Lateral X or a similar “gliding” machine that allows for more range of motion than a standard elliptical. Then, hop on an indoor cycling bike and do the prescribed routine.

This workout involves changing the revolutions per minute, the unit that represents cadence or pedal speed.
Total Workout Time: 40 minutes
Directions: Start the workout on an indoor rowing machine such as a Concept2. Set the resistance between 7-10 on an Concept2 brand ergometer.
Do the prescribed workout then move on to the wind resistance bike, which is a machine that has no motor and is powered by your arms and legs. The harder you pedal the harder it gets. Common brands are Schwinn, Rogue and Assault Fitness.
The measurement you’re going for on the bike is calories and while everyone has a different fitness level, 15-20 calories in two minutes is a good starting point. If you feel this is too easy, aim for 40-50 calories in two minutes.
Total Workout Time: About 35 minutes
Directions: This cross training workout requires you to go from one cardio machine to the next in a circuit format. Rest 1-2 minutes between each machine. More advanced endurance athletes can do 10 burpees, 20 bodyweight squats or 20 pushups between the machines.
Do this workout after a dynamic warmup since your heart rate should already be elevated past resting state when you begin.
