BAP - HELP

So I am playing BAP rookie season in Superstar because it is too easy otherwise, BUT I am spending way too much time spinning in a heap. I am not fast enough or agile enough to avoid hits, and the balance is so poor that every time I get hit I go down and lose durability, which is laughable to begin with.

I have found ways to increase some attributes during gameplay, but not acceleration, speed, durability or balance.

Can anyone help?
