Hi, I really need help and I hope someone out there can help me. Ive recently started working out at the gym and have been doing it for 3 days a week for the past 2-3 weeks. Now heres the problem. The first day I did 30 min on the stair climber and 15 on the bike.. the next day i felt sore and could feel my abs and my leg muscles, tight. And after that ive been doing weights.. Kinda like a ceruit type of thing and at first i did 1 set each then raised to 2 sets. I am not sore at all the next day and cant figure anything out. Seems like Im doing something wrong. I even changed the weights on a few and still nothing... The only plces i feel working is the arms and upper chest... Whats up with that?? Can someone please help??
