9. Dips

Dips's target muscles are low part of chest.
People usually do at the end of chest exercise.
Some of people do dips with hevy weight but normally people do just dips without weights

First, grab the handles and down slowly until feeling your low chest. Do not bend your elbow until your elbows are upper than your shoulder. Otherwise, it is so intense for the shoulder that you can't focus on your chest muscles.
Second, Strettch all your elbows and return your form when you start it.
Remember that stretch all but not until feeling your triceps because it can distract to concentrate on your chest muscles due to your triceps exercising.
