Gym is closed. Rest or go for a run. Low intensity active rest is a good alternative.
Do you think CrossFit prepares you for other fitness tests despite not particularly training for them? I believe so and have personally experienced it. Here’s an account from a friend of ours from North Scottsdale CrossFit who used only CrossFit to train, prepare for, and successfully run a 1/2 marathon. If you have similar experiences post to comments.
