Burpees make for killer shoulder workouts, but they’re also great for your core and cardio fitness levels. A burpee is a sequence of positions: begin standing, then lower yourself into squat position.
Place your hands flat on the ground and assume plank position.
Immediately return to squat position and jump back up into standing position.
Repeat this sequence as often as you can in your interval and say hello to a sweat you’ll never regret.
