Just a quick video on how to go from frog position to straddle planche and back.
You are going to get tired of me telling you to tuck your chest in, to push the floor harder, to lean forward, to round your back and contract your abs...but this is the way to do it...trust me, I have try a million way and this one is the easies and more effective...try it for yourself!
So, here we go...
Round your back by tucking your chest in and lean forward bringing your hip up... just over your head. at that point your legs still bend...now gradually start to open straight them back..note that at this point you have to lean forward a bit more to lever the weight. Do this slowly, take your time and feel what you are doing!
Go 4 it!!!
Have a go at this!!!
and see how it goes for you.
