Perform a Dip where you stop halfway down, then push back up, instead of going the full depth.
This is a good progression towards the full Dip if you don't have the shoulder flexibility and stability needed to go to the full depth (in Shoulder extension backward ).
Form tips
At the top, straighten your arms and push your shoulders down ( Shoulder depression ).
Your elbows should point more backward than outward (max. 45° out).
