CrossFit ATP’s Membership works on a commitment basis.  The longer you commit the more you are rewarded. We welcome new members to choose any commitment that they feel will best suits them. As nerdy scientists who love collecting data we have statistically observed that new members who initially commit to 6 months or more have over 90% higher success rates at achieving both their long term and short term fitness goals. In light of that observation we designed out prices to incentivize the optimal effect.
