I used to have the same problem, I could do series standing BHS with a coack/spotter nest to me, but when they left I could only do one standing and it went like straight up and straight down, killing all of my power. Start on a tumble track and warm up a few good ones and then, What I had to do was go onto a whale mat (i'm not sure what other people call them at different gyms) I think its a porta pit or something like this
one

except not in the middle of the wilderness lol. Then do a couple on their if you have one at your gym. It should be a lot harder to land but concentrate on technique, it doesn't matter if you land on your knees. Keep your arms by your ears, hands in and block. FOCUS ON TECHNIQUE!!! Hopefully this will help get you over the fear of falling/getting hurt. Once you are comfortable doing it there. Try in on a rod floor into a foam pit. At my gym we have a pit, and we put a mat on top and a panel on top of that. Like this mat, with a panel mat on top.

except for the small child and slide lol, im just having to much fun. Start on the rod floor and do your BHS onto the mat, it is a little harder than the whale mat but should still give you cushion. If it makes you more comfortable do it with a spot the first couple times. Try to land on your feet on here, it will be kinda hard but its possible.
Then get on a big cheese mat with a panel mat on top if its a super squishy, and do it on there, If you want a spot for comfort the first couple times, go for it. Once you are consistent on the cheese mat try it on the floor. Do it with a spot a couple times and then go for it.
A couple tips:
- Don't over think it, just sit, and go, you have the technique don't psych yourself out of it
- Tell yourself you can do it. It might sound cheesy but it should really help. If you have a positive attitude it makes a huge difference.
- Dont rush the steps. You wont be able to do all this in one day, just take it one step at a time and only move on when you are ready. if you rush though it it won't help at all.
- FOCUS ON TECHNIQUE, I can't stress this enough. It is all about muscle memory. Do it right when it's not on the floor, practice with the correct technique otherwise you will have to fix your technique later along down the road, It may not seem like a problem to do it sloppy a couple times on a whale mat, but you are only cheating yourself
- And most importantly don't get frustrated. This won't happen over night. You will have to put in the work. And one of my favorite pieces of advise, that I tell myself all the time, "you want it, you do it." Only you can make the change "nobody can want this for you"
And Most Importantly good luck to you:) I know you can do it, and I have faith you can make that level 3 team next year, just
dont EVER give up on yourself or your ability. I hope this helped!!
