In-Season Strength for Team-Sport Athletes: The Joint-by-Joint Model
How elite team-sport strength coaches structure in-season programming: the joint-by-joint model for deciding what each joint needs, and a lighter in-season strength dose that maintains rather than chases new gains.
Learn the joint-by-joint framework
Why ↓
Originally described by Gray Cook and popularized by Boyle: when a joint that should be mobile becomes stiff, or a joint that should be stable becomes loose, the body typically borrows movement from the joint above or below, which is where a lot of overuse injury shows up.
Cut total strength-training volume once competition season starts
Why ↓
In-season, the priority shifts from building new strength to maintaining what has already been built, without adding fatigue that hurts game performance.
Prioritize ankle, hip and thoracic-spine mobility work in the warmup
Why ↓
These are the joints the model treats as needing the most range of motion; keeping them mobile reduces the load a neighboring joint has to absorb.
Build knee and lumbar-spine (core) stability work into every session
Why ↓
These joints are more prone to overuse injury when they are forced to compensate for a stiff neighboring joint.
Program movements that transfer to the sport (change of direction, single-leg power) rather than a generic bodybuilding split
Why ↓
Team-sport athletes need transfer to the field or ice, not just bigger lifts in the gym.
Treat this as a coaching framework, not a proven physiological law
Why ↓
The joint-by-joint model is a widely-adopted heuristic among elite strength coaches, not something tested in randomized controlled trials; use it as an organizing lens for programming, not a guarantee.
The joint-by-joint model is a coaching heuristic, not an RCT-tested physiological law.

Is this for you
- In-season team-sport athletes and their coaches structuring maintenance-phase strength work
- Anyone wanting a joint-by-joint lens for organizing mobility and stability training
- Not a substitute for individualized coaching or a physical therapy plan
Cautions
- This is expert-practitioner consensus, a widely used coaching framework, not RCT-tested science; treat the joint-by-joint model as an organizing lens for programming, not a proven physiological law
- Boyle holds a commercial interest in the Certified Functional Strength Coach (CFSC) certification and MBSC's for-profit training facilities, online programs and instructional content; weigh that alongside his recommendations
- In-season programming should be adjusted by a qualified strength coach who knows the athlete's sport, schedule and injury history; this is general education, not an individualized program
- If you have an existing injury, work with a physical therapist or physician before starting a new strength program
