The anterior (front) deltoid: Helps with shoulder flexion and inward rotation. The middle (middle) deltoid: Responsible for shoulder abduction (lifting the arm away from the body).
The deltoid muscle is the muscle [1] forming the rounded contour of the human shoulder. It is also known as the 'common shoulder muscle', particularly in other animals such as the domestic cat. Anatomically, the deltoid muscle is made up of three distinct sets of muscle fibers, namely the anterior or clavicular part (pars clavicularis)
The anterior (front) and posterior (back) heads of the deltoid will also co-contract to aid in the abduction function. If the shoulder is laterally (externally, outwardly) rotated, the anterior deltoid becomes the prime mover of the glenohumeral joint, the posterior deltoid de-activates, and the middle head assists.
A slight variation in the lifts can hit the deltoids even harder, while moving upwards, just turn the hands slightly downwards, keeping the last finger higher than the thumb. This is an isolation exercise for the deltoids. Also works the forearms and traps. Equipment: dumbbells, cable machine or lateral raise machine.
The triceps are most crucial around the end of the press to help complete and lock out the elbows. With the right form, parts of the deltoids will be used to help make the lift, including the anterior deltoids. [6] Wider hand spacing places a greater emphasis on shoulder flexion and narrower hand spacing utilizes more elbow extension.

Close grip dips primarily train the triceps, with major synergists being the anterior deltoid, the pectoralis muscles, and the rhomboid muscles of the back. [1] Wide shoulder width dips place additional emphasis on the pectoral muscles, similar in respect to the way a wide grip bench press would focus more on the pectorals and less on the ...
