Although the best way to get better at grappling is with a real teacher and live training partners, sometimes you don’t have those resources available. There are times where you are at home and would like to try out some moves, and the Combat Sports Grappling Dummy is great for that.
The dummy is made out of synthetic leather, and comes in several sizes, from 70 lbs. to 140 lbs. These seem great for just pounding and throwing around as hard as you want. There is no fear of injuring your training partner, you can try some extreme stuff on these.
I can also see these great for some conditioning work. Try carrying it with you while doing short sprint intervals, then slamming them down, and then picking them up, pressing them, and starting all over. There are a bunch of workouts you would be able to do.
