Adding a suspension trainer to your bodyweight exercises is a great way to double the work and double the benefits. These trainers support your weight safely but will increase load on your muscles and joints in a way that will help you build lean muscle fast, while improving joint stability, flexibility and balance. You can suspend your feet and ankles to intensify the simple plank. Hold the handles and pump out skater jumps or squat jumps. Or use as a progression tool for advanced gymnastics movements. Whatever the exercise, you will feel the burn.
