Frequently Asked Questions

How do you switch between exercises?

Simply flip the handles — no tools required. The pivot point automatically repositions for the correct biomechanics.

What is the difference between cable flys and pec deck?

The pec deck provides a fixed, guided path that isolates pecs with less stabilizer involvement. Cable flys require more core/shoulder stabilization.

Can you use this for shoulder rehab?

Yes — the rear delt fly mode with light starting resistance and adjustable ROM limiters makes it excellent for rotator cuff and postural rehab.

Converging or linear chest press — which is better?

Converging arm presses better replicate natural human movement. The arms arc inward at the top, matching the path dumbbells take for superior pectoral activation and shoulder comfort.

Seated chest press vs incline chest press?

Seated (flat) targets overall chest. Incline shifts emphasis to upper chest and anterior deltoids. Most commercial gyms include both for complete chest development.
