One of the hardest things about mobility is coming up with the right exercises right when you need them. This is one of the primary problems Mobility on Demand attempts to solve. However, that doesn't mean that we've entirely eliminated the burden of figuring out which mobility exercises to do and when.
It is not uncommon that I will arrive at the gym with some extra time before the WOD starts and be stumped to decide which mobility exercises I should do prior to working out. Then, after the workout, it's common for me to spend some time on a foam roller, but not really with any purpose. Sometimes, I just end up sitting on my foam roller, chatting. Unfortunately, chit-chat doesn't make me a better athlete.
