I just did my first "climb" session. I need to get a cadence sensor, and I'm sure I'm putting on too much resistance. I was definitely fading at the end, but I feel good, now that my heart rate has come down. I really like the spin bike! Three sessions a week, with weights in between (I've increased my weights, so I do them "on the hoof," again), seems to be my sweet spot. I have maintained my weight, but my waist is slowly shrinking again, and my chest and biceps have gotten larger. More definition in my legs and arms. I will get the remnants of this belly gone, dammit!
