Mondays will be my crosstraining nights where I plan to experiment with different types of workouts and classes. I’ve had an indoor rockclimbing gym membership for half a year now, and I realized that I haven’t maximized its use to offset the monthly cost. I go to Rockreation over in West LA. It’s a great upper body and core workout, the gym environment is friendly, the music gets you pumped, and it exercises the mind by trying to get to a certain goal by trying different climbing routes. You can either rock-climb, where a partner is required to spot you, or you can boulder, which is my preferred choice of activity.
