pain

i was down the gym last night for the first time in god knows how long today and god i suffered for it today. legs and arms have been aching all day. on top of that it feels like some ones ripped my stomach out and tied it in a knot....very nice. after running about 8 miles (or for about 50 mins) to get down there i did a variety of exercises for upper, lower body and torso, including squats, calf raises, bicep curls, tricep dips, abdominal crunches, sit ups, seated leg presses and leg raises and some exercise where you are using one or t=other of your legs to lift your whole body up to the top of a step and bring it back down again whose name i can just never remember. i was in the gym for a total of about an hour and a half before i finally managed to drag myself home. doing back extensions for my final exercise was a mistake. i hadn't any strength left with which to lift myself off the floor. i jogged about a mile home but it hasn't seemed to make any difference to how i feel today. i'm just hoping that its because my body is temporarily unaccustomed to doing weight training, some thing that i hope to put right over the next coule of weeks.
