You're probably better off doing a strength-building routine, grip training, and regularly stretching than practicing grappling specific movements on your own. Hour for hour, you'll get more out of S&C than you would practicing shots, sit outs, and shrimps in your living room.
This is only really true for experienced grapplers. For people with less than three years on the mats (white belts), movement drills make a big difference in developing good muscle memory and instincts
I've seen the real life results. Two new guys join the club, one guy starts doing drills and studying youtube at home, the other keeps lifting weights. By one year in, the drilling guy is moving like a grappler and dominating his buddy, even though his buddy is stronger.
Speak for yourself; no one, not even God Himself, can break off my collar grip.Hell, anything is better than watching porn and jerking off I reckon.

EDIT: Plus if you do it to one of those videos where two ladies wearing none IBJJF approved gear try to submit each other it basically doubles as an instructional. Just... don't try to peg your opponents after you submit them like they do in those vids. I've been blacklisted from so many places for that.
