Im about 6 weeks into my first cycle(500mg tes e wk). I decided to bump my cardio up to 5-6days a week to keep the water weight down and also help my body adjust to drastic increase in body weight.(wont lose my breath going up a flight of stares) I can do the elliptical 30 mins keeping my heart rate at 140 with no problems. but every time i try to run i get this crazy painful pump in my shins and sometimes lower back after about half a mile. I made my self go a mile in 10 minutes and i could hardly walk after... i could do 2 miles easy last time i ran (about a year ago). I talked to one of my cross country running friends and she said its not shin splints. my weight is up 25-30 pounds from the last time i ran, only thing i can figure might cause this. or maybe some deficiency, but i am eating 45-5000 cals and drinking 1.5-2 gals of water a day. fyi
any thoughts?
