Swim-Lift-Bike-Run

I hit the gym on Sunday morning for a 1/2 hour swim.  Swam 1200 yds and kept the HR at around 150.  Felt pretty tired after the party on the night before.  However, by the afternoon, I was ready to go back to the gym to lift-bike-run.  I bumped up the weight on the squats and felt a bit more pain throughout the workout.  Used 150 lbs on the squats, 35s on the step ups and 25s on the lunges.  The entire lifting sequence took about 35 min. and I hit a max HR of 188 during the lifting.  My average HR was 146.  I then did a 15 min. bike with an average HR of 119, and a 15 min. run with an average HR of 140.  Felt really good in this workout.  Also felt the stress in the legs and it took me about 1 and 1/2 day to recover.
