Sunday's Gym Routine; end of a 12 day cold?

I was finally feeling like a normal human so Sunday I returned to the gym. I hadn't run in a long time and I have new running shoes, so I wanted to add some running.

2. Hip ADDuctor machine, 20 reps with 250.
3. Hip ABductor machine, 20 reps with 250.
4. Single-leg leg press, 20 each leg with 50.
5. Seated cable row, 20 reps with 42.5.
6. Back hyperextensions, 20 reps with zero weight.

4. Seated cable row, 20 reps with 42.5.

Hot tub for 20 minutes, felt REALLY REALLY fatigued. Workout was more than an hour, Polar Watch said I burned 750 calories. During leg press sets my HR nailed up into the 160s. FYI my average heart rate during my last 2 functional threshold of power tests was 164 and 165.

I do high reps because I am done with the previous phase that was MAXIMUM STRENGTH. I do these reps more quickly than before.
The goal with a routine like this is to keep the strength from the previous phase while I return to on-the-bike training.

Now I'm going outside to ride....
