Anon Front tuck step out help!

[gymgem0000]

I'm having a really hard time getting my front tuck step out, I can't make myself step out. My front tuck is fine, and I have my step out on the tumble track, but I can't get myself to actually step out of it on the floor until I have basically already landed, which is obviously too late lol
Are there any drills that could help me? For front tuck height and timing especially! My coaches haven't given me any drills except trying the actual skill in the floor and the tumble track. I would love any help and advice! Thanks in advance
