Swish

Film 10 shots

Trainers: you cannot watch every rep between sessions, so you walk in guessing. Players: you put in the hours and still cannot tell if you are getting better. Ten reps on film give you both the same number to work from.

Prop the phone back far enough to see the whole body, head to feet. I will tell you live when I have you. Film one shot at a time. Ten is a session.
