Crab vs. Bear Soccer

Preferably played on a soccer field with goals, divide into teams, one team has to crab walk while the other has to bear crawl. Once someone scores a goal, then the teams swap roles (bear to crab and crab to bear). Goalies have to plank, and goalies must be swapped out after every goal scored. Play for as long as you want, real men play for at least 20 minutes.
