Trying to Train Smarter, Not Just Harder

Weights of course, first thing. Trying a new thing - instead of 2 sets of 12 and then 15 reps, doing a bit heavier weight, so that it is pretty darn difficult to lift on the last rep, and doing 8,6,4 reps - twice through if I have time.
Workout today was STATIONS again - always on Tues & Thurs mornings in the summer, I suppose.
