You can run in the gym before breaking of fast. Really respect you. I see my neighbourhood kids playing football before breaking of fast too and I truly admire them.
Even those Muslim professional footballers playing in Europe will fast during Ramadan, and there's no problems for them to maintain the same regime. Supermen, those guys. When there is a will, there is a way. ;)
Yes, agree with you... with determination, one can do it! Syabas, Lina!!
