Is stretching before BJJ needed?My class has no stretching before class and I always am cramping.I'm 48 and need some advice on whether I should quit and try something else.When does it become too old to spar in muay thai?I was told I could'nt spar before.Got all the training I need and further classes are'nt teaching me anything.need to spar to get any better.My motoviation is at an all time low now.
