Cable crunch
Set up a repeatable loaded crunch, distinguish trunk flexion from hip motion, and progress it without chasing stack weight.
Cable crunch guideExercise database
Exercises explained without fake precision.
Each guide connects setup, execution, muscles, common mistakes, progression, alternatives, and the limits of the available research.

Editorial standard: an EMG result can describe electrical activity during one protocol. It cannot by itself prove long-term muscle growth, the perfect technique, or the best exercise for every lifter. Related-exercise evidence is labeled rather than presented as direct proof.

ChestDumbbells
Incline dumbbell press
Choose a repeatable incline, track chest and triceps work, and understand what bench-angle studies actually show.
Incline dumbbell press guideBackCable
Lat pulldown
Use a stable front pulldown, compare grip-width evidence, and stop assuming that the widest grip must train the lats more.

Cable lateral raise
Keep the setup reproducible, manage load and range, and compare cable and dumbbell evidence carefully.
Cable lateral raise guideBicepsCurl
Preacher curl
Stabilize the upper arm, record the implement, and see how cable and barbell resistance profiles differ.
Preacher curl guideHow every guide is built
Repeatable execution
Setup and range are written to make sessions comparable, not to declare one universal form.
Evidence with boundaries
Each page names the participants, protocol, result, and limit of the most relevant studies.
Progression in context
Load, repetitions, sets, RIR, and equipment stay attached to the exercise that produced them.
Connected topic graph
Exercise pages link into muscle recovery, weekly volume, RIR, and progressive overload resources.
