Many men don’t like Swiss balls – they feel that men should use heavy things made out of iron. If that has been your opinion, this workout may just change your mind. It requires you to perform six exercises back-to-back, testing a different part of your body with each one, but always making you work those core muscles to keep your body stable. Complete the circuit with strong, controlled movements and you’ll get a full-body muscle burn and good cardio workout to boot.
