If your baji training doesn’t start with the proper way to measure your horse stance and it explanation of a triangle formed by the buttocks to ground, thighs and calfs, I would question them very closely. Also, most training starts with the stationary one punch and the moving one punch. Contrary to most, you don’t start stomping right away.
They also should take you into single moving postures which build directly into the xiao baji form. Don’t worry about counting breaths right away. Get the structure and relaxation first.
Follows the taiji principle, first expand the body then it will naturally contract (big movements, then small movements come naturally) [terrible paraphrase of the quote].
Here is a list of schools but there is variation among schools in training and material.
