I used to walk on my breaks where I worked several years ago, but since I got let go, I just can't seem to get back into the routine. I'm a yo-yo dieter and am constantly trying to lose weight. How can I rev up my metabolism? I've gone to Weight Watchers and love their program(s), but right now I'm not financially able to attend and my weight has crept up to 195 (again). I also need to do exercises that fit my health issues (bladder leakage; 25 lb weight limit, etc). My willpower has literally gone out the window. Any suggestions?
