Machine Chest Press vs Free-Weight Bench

A seated chest press machine guides the weight along a fixed path and braces your torso, removing much of the stabilising demand of a free barbell. As a result you can usually move more on the machine. A common rule of thumb is that your barbell bench is roughly 80–90% of your machine chest press.

Questions

Chest Press FAQ

Why can I press more on the machine?
The machine stabilises the path and your body, so your prime movers do less balancing work and more pure pressing.
Is the conversion exact?
No — plate-loaded, cable and selectorised machines all behave differently. Use it as a guide and verify with a real barbell set.
