Your training program is well complemented by vertical push-ups on the bench. The exercise not only well compensates for the lack of load on the middle bundles of the deltoid muscles with ordinary push-ups from the floor, but also develops all three heads of the triceps, with an emphasis on the middle part of the muscle. Bench push-ups should be included in your workout if you want to build mass and thickness in this muscle.

Performing vertical push-ups, make each movement as clear and smooth as possible, but without jerking. When performing the exercise, do not spread your arms to the sides, lower them down so that you feel the tension of the triceps well. In this case, the quality of performance is more important than the number of exercises done. To increase the load when doing push-ups on the bench, ask your partner to put a disk on your hips.
