Just go one or two rounds of slap bag with Jess and you'll be set.
okay, I feel like I post a lot of pictures, but I enjoy visuals so I'm sorry to all if it's obnoxious.
BUT. I did some master-level bag slappin' last year that we should definitely attempt. we had a train of 5 people at one point and it was amazing. (that picture is shit, but this one gives a good idea of the bag slap train)
