hey man do warm up and stretch. i was late to class(like always) and i hopped in to do a couple rounds of randori. my sensei asked me if i need to warm up first, i told him that i was ok.
my team mate shot in for a single, i stuffed it, but he still got a grip low on my ankle. i turned my back to him to step out. when i was drawing my foot from his grip i felt my knee come apart. i scared the shit out of me. i warm up every since then.
