In reply to EmSB:
If you do dips to build strength and stamina in your triceps, don't lower all the way down, as the last bit can get you badly injured.
If you have access to a fitness gym, there is often a machine that enables you to do assisted dips, and pull ups.
But press ups, and shoulder press with dumbbells will be great both for triceps, and building essential shoulder stability, warding off common shoulder injuries.
Resistive bands could be used for triceps too, ( and for rotator cuff exercise... Shoulder stability again).
Don't hang fully extended on your shoulders doing pullups (injury potential)
This Robbie Philips series is helpful too...
