CF:
Overhead squat 3-3-3-3-3 reps
Level 3: If mobility/positioning/strength allows, go as heavy as possible, building each set to a 3rm.
Level 2: If newer and not as confident in OHS, stay at a light/mod load and drill positions so that each set of 3 across are consistent.
Level 1: If mobility/positioning/strength dont allow for OHS strength development, work on sets of 3 back squat with moderate load, concentrating on specific mobility pieces between sets to improve ankles/calves/t-spine/shoulder
