Strength Training Without Losing Mobility

Discipline 5: Physical Performance — Lesson 7 of 12
Lecturer: Douglas Kerr

Strength without range of motion just becomes stiffness. This session covers pairing strength training with mobility work, training through full ranges of motion, and periodising heavy strength work away from technical training weeks.

The three rules

1. Pair strength with mobility.
2. Train full ranges of motion.
3. Periodise around technical weeks.

*The full breakdown — citations, the lecturer's own story, and the discipline's quiz bank — is part of the Spy Academy programme.*
