In the internet we can see only guys doingcalinethics, and I could not find any girl doing this sport. Is thereany reason why a woman would not do this sport? Or I just did notlook for them well enough?
Sincerely, I am not sure why there are so few videos with women practicing calinethics, but there is definitely nothing wrong with it for women. You can surely practice this sport without any problems. It may be a bit more challenging for a lady in the beginning, but for each exercise there is a simplified version which can be easily executed by the novices.
I think you are just looking in the wrong places. As @stevesmi mentioned, a lot of females perform calisthenics workouts.
Especially things like pilates, yoga etc. all incorporate calisthenics. All calisthenic workouts mean is a workout that uses nothing but your body weight.
