Its called grappling/wrestling sport for a reason, so make contact, and try something. Dont
1 Push off when someone comes close to you.
2 Use the whole mat to run away
3 Don't stiff arm the whole standing.
4 Don't hang onto thai clinch for dear life, it aint thai.
Try a wrestling move, a judo throw or pull guard. You cant get punched, so no need to get worried.
Dont walk backwards, for every step you walk backwards, i will set a house on fire.
