I've been doing crossfit for two years and have enjoyed getting stronger and fit. But I'm getting older (59) and I'm not enjoying the gymnastics, box jumping, and other stuff that's hard on my joints. So I'm looking for an alternative that will include strength training and some cardio. I did orange theory for 2 years prior to crossfit but left because I wanted more focus on strength training and less cardio - I got some overuse injuries from so much time doing inclines on the treadmill. I'm not disciplined enough to follow a program on my own at the gym, so i would like a class environment. F45 looks interesting, but I wonder if it's too similar to orange theory. Does anybody have suggestions?
