Strength is the maximal force you can apply against a load. Training to improve muscle strength and appearance includes lifting weights and increasing the resistance against which your muscles can work. Power lifting is a strength sport that will test your strength in bench press, squats and dead lifts and bodybuilding is based on aesthetics.
With the introduction of machines, we have noticed the importance of overhead lifting gradually diminishing, especially by the novice. The benefits of overhead lifting go unnoticed by many fitness freaks training in the gym, who are just concerned with - how the body appears rather than 'performance with appealing looks'.
The standing overhead press proves to be a great exercise with just any sport, in which you have to transmit force from the ground through the core muscles and finally into your arms. This can include anything from throwing ball in cricket, to pushing against an opponent in a sport like rugby or football. Since you are standing unsupported and not leaning, they also target your stabilizers as well as point out any weakness in the trunk region and in the long run, one can actually experience the weak muscles of the back, getting strengthened while performing 'Activity Of Daily Living (ADL)'..
