1. Dips
Bench presses and all the different variations are good if you want to build mainly a bigger chest but you should also think about doing dips if you really want to build muscle fast and improve your physique.
Start off by doing bodyweight only dips and once you can do more than 10 bodyweight only dips then you can move on to doing weighted dips to really pack on muscle mass in not only your chest but in your arms and shoulders as well.
Bonus tip for dips: The more you lean forward while doing dips will give you a better chest workout and the more you keep yourself upright will give you a better triceps workout and don’t listen to anyone who says dips are strictly for your lower chest.
