When your muscles are stretched, their ability to generate force decreases due to the alteration in the optimal length-tension relationship. Muscles produce maximum force when they are at a specific length, and excessive stretching can place them beyond this optimal range, reducing their efficiency. Additionally, a stretched muscle may not engage its full contractile potential, leading to decreased strength during lifting. This biomechanical limitation explains why you can't lift as much when your muscles are overly stretched.
By trying to lift too much weight.
Uh all of your muscles DO work together, when you move or lift things......idiot
stretched or excersised.
Improve your mobility.
A muscle pull happens when muscles are overworked or over stretched
passive stretching
It can be, because if your hands are to close together, you are isolating muscles, make it harder to lift. If the weight is distributed over a wider range of muscles, or stronger muscles, the lift is easier.
The shoulder muscles
Impossible to tell, since that will depend on the tone of his muscles.
your muscles burn when you exert yourself because when you lift heavy or lift for an excess ammount of reps you get a build up of lactic acid in your muscles
Your arm muscles work by contracting and releasing to lift a mug of coffee to your lips. The muscles flex and contract to move your arm.
We have muscles so you are able to lift things and do everything we do on a daily bases .
