I do a variety of exercises. I do a mixture of H.I.I.T, crossfit, and weight training. I love the thrill of pushing my body to its limits and working as hard as I can. Someone mention doing inside cardio is boring. Of course it would be if u sat on the bike for 30min. Try H.I.I.T u will love it and definately won't get bord I can promise u that much.
