Muscles involved: Latissimus dorsi, teres major, finger flexors (flexor digitorum superficialis and profundus and flexor hallucis longus), flexor carpi ulnaris, long and short palmar muscles
While standing, preferably in front of a mirror, raise your arms above your head, with fingers interlaced and palms facing upward. Just stretch as if you are trying to reach the ceiling.
This exercise also involves the flexors of the hand. Unlike some previous exercises, this is an exercise that can be performed by people of advanced age and those with certain physical disabilities, depending on the type and degree of the disability. These two groups of people can omit interlacing the fingers if it presents a problem.
On this exercise, some people tend to stand on the tips of their toes, trying to stretch even more parts of the body. While not harmful, it may prevent the person from concentrating and thus compromising his or her stability.
