I'm 31 yrs old. I recently had an inner thigh injury but am rehabing that. It's feeling stronger already. What I'm already doing is stretching my legs every other day. I normally will do 20 min on exercise bike then stretch since I heard it's better to stretch once you are warm. I've been stretching my legs regularly for the last 2 months but off and on for the last 6 months and I feel like I'm not getting anywhere. The injury didn't help I guess. Do I need to stretch everyday? Do I need to stretch maybe twice a day everyday to increase flexibility? I'd like to be able to kick near head-level again like I did as a teenager. I can't kick above the waist right now. I also have shorter legs due to genetics. Anyone increased their flexibility have recommendations?
