Looking for a workout that strengthens your whole body, requires no equipment, and delivers major health benefits? This intense 650-rep bodyweight challenge—originally a tribute to fallen U.S. Army Sgt. Zachary D. Tellier—pushes your physical limits while supporting cardiovascular health, muscle endurance, and mobility.
The structure is simple but effective: five rounds, each one adding a new movement. It starts light with burpees and ends heavy with 150 squats. While it may sound intimidating, you can scale the reps or take breaks as needed—just focus on form and consistency.
Why This Workout Is Great for Your Health
This isn’t just about bragging rights. Each movement targets a specific muscle group and promotes full-body strength:
Burpees elevate your heart rate quickly, improving cardiovascular endurance and calorie burn.
Push-ups work the chest, shoulders, and triceps—supporting upper-body strength and posture.
Lunges enhance balance, leg strength, and hip mobility, all of which are key for joint health.
Sit-ups target core muscles, which support spinal health and help with stability in daily life.
Squats strengthen the glutes, quads, and hamstrings—essential for everyday movements like standing, walking, and lifting.
This no-equipment workout also improves functional fitness—helping you move better, feel better, and reduce injury risk.

Complete for time, resting as needed between movements:

How to Perform the Movements Safely
Burpee: Start in a standing position. Drop into a push-up, then jump back up, clapping overhead. This move improves heart health and coordination.
Push-up: Lower your chest to the floor and push back up, keeping elbows tucked in. Builds upper-body strength and shoulder stability.
Lunge: Step back, lower the knee, and return. This strengthens legs and boosts balance.
Sit-up: Keep your core tight and avoid pulling your neck. Strengthens abs and supports spine alignment.
Squat: Drop low, keeping chest up and knees behind toes. Excellent for leg strength and metabolic health.
Science-Backed Health Benefits
This workout isn’t just a sweaty challenge—it’s a serious health booster. According to research from the American Council on Exercise:
High-rep bodyweight training improves cardiovascular endurance and metabolic health.
Movements like squats and lunges increase bone density and lower body strength—critical as we age.
Core-focused exercises like sit-ups improve postural support and help prevent back pain.
Burpees alone can burn over 10 calories per minute and improve VO₂ max, a key indicator of aerobic fitness.
It also promotes mental toughness, which plays a role in managing stress and building confidence.
Final Word: Know Your Limits
This workout is safe for most healthy adults but may be intense for beginners. If you’re just starting out:
Cut the reps in half.
Skip a round or reduce the sit-ups and squats.
Focus on perfect form over speed.
Always consult a healthcare provider if you have underlying health conditions or concerns before starting any new exercise regimen.
