Alright... I been doing some light weight workouts for four days now. all of them between 45 to an hour long. i would of thought by now i would have some muscle pain. I do weight lifting 15 reps with 2 sets. I also do core, back, and arm workouts. Like I said im not as sore as i am when i go to the gym with my personal trainer, why is that. am i not pushing myself hard enough. Not doing them right. Or should i just extend my workouts?
