LBTC's recovery advice is good! I agree that after a TOUGH workout, the soreness doesn't strike me until the second day after as well. This means that you were hit with your soreness from the first workout right about the time your muscles are trying to recover from the second one! I found that as my body got accustomed to weight training (after long periods off), that the soreness hit sooner (and therefore also went away sooner).

It won't be long before 48 hours is plenty of recovery time (assuming you are fueling correctly). The first few workouts are always the hardest to recover from!! Hang in there!
