Re:Ripped in 30
I have been working out a looooong time (I'm 50), but I'm not an exercise professional. However, from everything I've heard and read about weight lifting, you should not exercise the same muscle groups every day. It's OK to use weights everyday, as long as you are working different muscles on each day. Muscles need to have time to "repair" from the strain of lifting heavy weight (at least 48 hours) in order to build up.
