I never get sore after lifting wieghts. i used to life them a lot, then get sore the next day or so. then i got lazy for a few months and stopped lifting. now im starting up again but i dont get sore afterwards. am i doing something wrong? im drinking protien shakes afterward(something i didnt used to do), so maybe that's a contribution? i was just wondering if not getting sore meant that you're not getting results. or if anybody knows if im doing anything wrong. An example of one of my wieght workouts: Start with 12lbs and do 15 reps of bicep curls, immediatly after (pyramiding) i do it with 8, then with 5. Then i take about a 20 second break in between and start again. i usually only end up doing 3 or 4 sets. is that my problem? am i not doing enough?
