Transform your lower body strength, endurance and power and reshape the way your cardiovascular fitness works with a workout that raises the temperature just as it challenges your ability to maintain quality of movement over the entire workout. Heart Breaker is definitely not a workout for the faint of heart. Go high in the jump squats and deep in the lunges and add EC to totally test your body's ability to recover on the fly.
Extra Credit: 1 minute rest between sets.
