“Those are pretty popular now,” Szekretar says. Functional fitness means doing exercises that improve the overall balance and coordination of your body. Use your own bodyweight and maybe grab a Bosu Ball. TRX programs are another good example. You use your own body for strength exercises that increase endurance and flexibility so your body has a wide range of motion. All of this helps you perform everyday activities easier. Use a ball with TRX Suspensions and resistance bands for a stealthy sculpting session that is sure to give you cuts in all the right places.
