Barbell Glute Bridge

Trains glutes first, with real work landing on hamstrings, core.

Muscle contribution per set

Glutes1
Hamstrings.25
Core.15

These are the weights Forge's volume audit actually computes with — deliberately conservative, so compounds don't masquerade as full coverage. A 0.5 means a set counts as half a set for that muscle: meaningful help, not a replacement for direct work.

Top pause + controlled eccentric maximises glute maximus recruitment in shortened position.

How Forge progresses it

Progresses by load: +2.5kg the session after you earn it. The engine watches your reps and how hard the top set felt before adding.

Swap it for

Same movement pattern, same progression continuity — these are the alternatives the app offers mid-session when a rack is taken or equipment isn't there.

Train with intention. Open Forge — it prescribes the weight, watches the reps, and does this arithmetic for every set you log.
