My coach/ gym adds a fair amount of catch wrestling submissions along with classic wrestling takedowns from standing.

I did judo for a while and dabbled with some sambo guys (my leg lock game is nothing to brag about). I wish i could do all three but BJJ is the one for me at the current moment.

I don't feel like I'm really cross training between bjj and judo. I think of it as training for different competition rules for the same martial art.

I crosstrain in Judo, Sambo, and Luta Livre. More seriously in Luta Livre of recent, Sambo has been my main form of crosstraining for quite a few years.

I'm training Judo and Wrestling aside from Jiujitsu. At first I was in for supplementing Jiujitsu but I fell in love with both grappling arts as well.

I recommend for everyone to learn another grappling art apart from Jiujitsu.

I always wanted to pull off some BS pro wrestling moves during rolling

I do the Walls of Jericho all the time. Single crabs are actually much easier to get though.

There's actually a pretty legit entry into a single crab from the left arm going under the left side knee grabbing your right bicep and right hand on their left side knee and just rotating them over to the left and sitting down. More of an entry into calf slicers instead of rotating them over but the Walls of Jericho is more fun and the calf slicer is still their if you screw up lol
