Last week I joined a new city-owned gym (yay!) that just opened near me. I've committed with a friend to work out M-W-F mornings for about 1 1/2 hours a day. I start out with a 20-minute warmup on a recumbent bike, and then have about an hour to do weights. On T-Th I usually go for a long walk, and usually walk or hike again at least one weekend day.
The question is, does anyone have suggestions for maximizing my workout? I have two goals--first, to get strong enough by July to row a raft on a river trip (not too strenuous, but still pretty physical), and second, to support my weight loss efforts. Right now, I've found weight levels at which I can do three sets of 12 reps, but I'm only working my upper body; I run out of time before I get to my legs. Would it be better to drop the third set, or should I just leave my legs alone? I've got to say, I love the upper body workout the most, but is that silly?
Any advice would be absolutely welcome!
