Push ups, dumbbell press, dips, and machine chest press all train the same chest, front delts, and triceps.
Any horizontal or downward press hits the same muscles as the bench, the chest, front delts, and triceps. Best direct swaps are the dumbbell bench or floor press, weighted or bodyweight dips, machine chest press, and weighted push ups. Dumbbells give a longer stretch and fix side to side imbalances, while dips bias the lower chest and triceps hard.
Dumbbell bench press closely mirrors the barbell version but lets each arm work independently and stretch deeper, which many find better for chest growth. A floor press is a good option if you have no bench, limiting the range and sparing the shoulders.
Weighted or bodyweight dips are a heavy compound for the lower chest and triceps. Lean your torso forward to bias the chest, keep it upright to bias the triceps, and add weight with a belt once bodyweight gets easy.
Machine chest press or a cable press gives constant tension and is easy to push near failure safely without a spotter. Weighted push ups (feet elevated or with a plate on the back) scale surprisingly well and travel anywhere.
