SC, I've added weight training to my regimine, and I've noticed a considerable improvement. Since the fall, even with Thanksgiving and Christmas and a NY vacation full of bagels and delis and diners, I'm still down weight and noticing I fit into old clothes I'd almost given up on. Eating well, and, I'm sad to say, biking, without the weight stuff, never worked this well for me. Seems like I need to put them all together. That's just me.
