Stephanie Tallant and Coach Tiana I have actually problem with my flexibility, which got worse after I started regularly going to the gym and lifting heavy weights (4 weeks - 2x lower body, 2x upper body). Even though I'm currently trying to include flexibility at least 4x a week, I still feel like it's just not there. First, I have a problem with the front and middle split. Somehow I hit the ground running, today the hamstrings are pulling me very hard. Should I include some extra stretching or warm-up for example on the roller after strength training or after my cardio sequence (50 minutes of skipping every day). Roller is very popular now, but I don't know if it will help. I'm desperate about it. Thank you very much!
