If it's too easy, then add weight. I find an occasional body pump class really helps my endurance with heavy weight. I notice the difference when on hills and trying to maintain max speed for a distance when road biking and noticed it helped when I packed my last elk out. I usually do around 100 pounds on the squat set and also heavy on the lunge sets.
I meant it was easier to get up at 430 on a work day and go to the gym than I thought. The work out hurt as usual. I am near max for completion on all segments except shoulder. I have a partial RTC tear on the left.
