TRX is a great home gym equipment that makes simple exercises a little bit more complex. How Randy Hetrick designed it, Is to accommodate his daily army-style workouts. TRX works on using your own bodyweight to perform exercises (over 300 exercises) . You anchor the strap either on your ceiling or your wall and you’re set. You adjust the strap’s length for more difficulty and resistance then workout pretty much any muscle. The more challenging your workouts the more calories you’ll burn.
