i have weak arms. i am still researching on weather i want to pursue body building. but in the meantime i heard calisthetics is a good form of exercise especially for your arms. i cannot access a gym right now, so what are some good body weight exercises?

is it a waste of time if i want to get strong. (i am disabled and am an easy target to thugs so i need to get strong).

do i need a plan?

should do idk

10 pushups

10 bushups from a bench (in sitting position)

and idk maybe 10 chinups

thanks for your time
