You can also add weights to your dips. Wear a rucksack and add plates in it. By doing this the body weight increases and more pressure is put on the shoulders or triceps or the chest. Thus they show better results.
8. Belt + chain weighted dips
This is the best way to do weighted dips. Wear a dipping belt and through the chain attach plates to it. This increases body weight from the center and works best for the chest and the abdomen.
