Accommodating resistance

Why it matters for online coaching

Powerlifters and strength coaches use bands and chains to overload the lockout and teach bar speed. The bar accelerates through the sticking point because the load climbs as the lever arm improves. That is the whole point. The strength curve and the resistance curve finally line up.

For a remote client, though, this is a variable that needs clear written instructions and often a video. The setup is easy to get wrong. A band anchored to the wrong point on the rack changes the curve you wanted. A chain that piles too high deloads too much at the bottom. The note has to specify the band tension or the chain weight, the anchoring point, and how the client should feel the difference at the top.

Bands versus chains

Bands add a speed-accent and a deceleration component at the top. The band wants to snap back, so the lifter has to actively pull through the lockout rather than coast. Chains add weight through the concentric in a smooth curve, loading the top without the elastic snap.

The choice depends on the lift and the goal, and both need anchoring. Bands choked to the base of a rack suit squat and bench. Chains draped over the barbell suit deadlift work where the floor takes the chain at the bottom. Get the anchoring wrong and the curve you programmed is not the curve the client gets.

How it shows up in coaching software

The editor takes a band or chain note per set. It is a field, not a calculation, and the coach writes the setup in the notes. The software does not know what a mini-band choked to the base of the rack weighs, and it should not pretend to. The coach logs the tension or the chain weight as the client will read it.

This is the same pattern we describe in how we build client programmes. The set carries the load marker and a free-text note for the setup. Reusing the band prescription across a strength block is covered in repeating workout programmes, which is where the note field earns its keep.

Who it is and is not for

This is a tool for strength blocks on the big lifts, not a general-population default. A client working hypertrophy brackets does not need a band on their bench press. They need clean reps and progressive overload. Accommodating resistance lives in the heavy 1 to 5 bracket where bar speed and lockout strength are the limiting factors.

Where that bracket sits in a programme, and why it is narrow, is set out in rep ranges. Most online clients never train there. The ones who do are usually powerlifters or strength athletes with a coach writing the band tension for them.

Where this is drawn from

Accommodating resistance is associated with the Westside methods developed by Louie Simmons, who imported band and chain work into conjugate periodisation through the 1990s. The formal treatment appears in the NSCA's Essentials of Strength Training and Conditioning, which covers the strength curve and the resistance curve as paired concepts. The narrowness of where this belongs in programming is ours. The physics is not.
