So, I've been taking workouts so far on Wednesdays (cardioblast), Thursdays (pump 'n' jump), and Fridays (yoga). Tomorrow I'll be going to my first Total Body Workout. If it is like the other cardio classes, it will kick by arse, but I expect it to work me out quite nicely, helping me take down my weight further. I've already lost ~10lbs over one week.
True, the first week back to working out is the one in which you lose the most weight, but it is nice to be under 250lbs again. Let's just see how much I weigh after another month. Of course, I'm not doing it for the weight loss, per se, but because I'm wanting to just work on becoming more aerobically fit.
