I am midway through a test cycle. I have been putting on amazing gains and my strength is through the roof. I found out last week i was accepted into a highly strenuous military specops program later this summer. I need to up my cardio and swimming. I used to be a decent runner, but i have done zero cardio since i started my cycle.
I jogged a half mile and my calves were in excruciating pain. I am wondering if this is due to sudden weight gain and my legs not used to operating with it, or if muscle growth in my calves have created some kind of situation. If anyone knows please fill me in.
