Tricep extensions are almost identical to the skull crusher exercise apart from instead of lying down you perform this exercise either sitting or standing up straight.
- Compound
- Dumbbells
The move is really simple and can be done either at the gym or at home. If you don’t have a dumbbell this exercise can be performed with a weight plate or even a heavy enough object.
