Bench dips:
Sit down on a bench, hands next to your thighs. (You can also perform a bench dip off a stair or other elevated surface; the same steps apply.) Walk your feet out and extend your legs, lifting your bottom off the bench and holding there with extended arms. Hinging at the elbow, lower your body down as far as you can go. Push up through your palms back to start.
Mistakes and Recommendations:
It is not recommended to put your hands too far from each other. It may lead to an elbow injury.
Try to find a convenient angle in your elbows.
Make a pause for 1-2 seconds, exhale and return to the initial position.
