I sometimes train at school in our wrestling room. We have some 100lb grappling dummies that work great for striking when set up against a wall or somehow supported. They are strong enough to stand alone if they're balanced. I seem to have invented a drill where I balance them to slightly begin to fall forward and throw Jab-Cross combos to try to keep it balanced. If it comes to far forward, I throw a knee or hook and let it fall and cover it to take the back and transition to mount, then start again. If I jab-cross too much and it goes backwards, I throw a body or leg round kick and cover it, and start again. When I 1-2 I back up a little so I don't throw it all the way over backwards, they're pretty heavy but I'm an athletic 215 pounds with a lot of snap and power. Does that sound like a reasonable drill to do when I don't have a partner? Or is there something that could tweak off my game?

Thanks. It's one I can really focus on techinque. It's helped me speed up my bob and weave and head movement, because I need to keep the dummy balanced, but also work movement and footwork.
