For referencing, you just videotape it and then you post it up here.

Ok i will post it up soon

This is something that just takes time to learn. Even nowadays I think that sometimes I will be horizontal while really there is an incline while in BL. It's pretty to tell if you are horizontal in a FL but trickier as I said in the BL.

You may just have to tuck on doing FL negatives for now. Get upside down in tuck and try to lower down for 3-7 seconds. I like negatives to be at least 3 seconds but they could be up to 10 really (which if you could do you would you probably could the tuck FL).

Body Lever is a good exercise in itself. You may find that you are unable to lower down to horizontal and hold and that's ok.
