Removing a BB

While this is a Lemond Revmaster (Sport) spinner bike, I believe that the basic structure is the same as a conventional road bike.

I am trying to remove the BB assembly (to be replaced) and have the cranks removed and have the right BB remover tool. I've never done this before. The tool is this multi-toothed thing where the teeth slide into 'their mates' in the BB cups. According to the instructions the right side is reverse threaded so I have been careful here.

But with my not that big 1/4" socket drive (that fits into the BB cup remover tool) I really can't confidently hold the tool in place while I put about about a billion foot pounds of torque into this thing. I'm afraid that I am either going to ultimately tear up tooth things as I can't securely hold this tool in place and the tool has a tendency to kind of twist/pop out under heavy (one-sided) applied force.

Is there some technique here? It seems like I need some kind of socket drive where I can apply torque from two sides so the thing doesn't have this tendency to slide out.

Also the left side did budge a little bit. But it felt like I was tightening it (I was going counter clockwise). After just a hint of turn that same force will no longer do anything. So I am proceeding very cautiously here for fear of really messing something up.

Thanks.
