Okay so I'm a 14 year old female. I weigh about 120 lbs and I'm 5'5. I play basketball, but I'm not very good. I have really low stamina compared to everyone else on the team. I need exercises that can help me build muscle but still be flexible because I dance and we have to do splits and things like that. I'm also interested in healthy eating habits and yoga. Also I'm trying out for my school dance team in April. What are stretches that can help prepare me? Thanks so much!
