Regarding injury avoidance:
1. Screen all clients in basic movement assessment and structural balance.
2. Address unbalance first, particularly in the shoulder/scapula.
3. Teach the basics and require steps. If you cannot perform a strict pull-up, do not perform kipping pull-ups. If you cannot properly rack a front squat, do not perform thrusters.
4. Balance in programming, particularly between strict vs. kipping volume, as well as horizontal pushing vs. horizontal pulling.
5. Accept that some isolation movements - even those moving small loads very slowly over a small distance - have a place in a sound training program.
6. Do not exceed 60 minutes of high-intensity conditioning in any given week.
7. Demand full range of motion at all times.
