Yesterday I went to the exercise room at my apartment complex, and all of the equipment was turned off, with the mats that were previously under the machines was laid out in the middle of the floor. It smelled very strongly of mold and mildew, and the apartment office was closed so we couldn't find out what was going on. So, my fiance's mom (she wants to be my accountability and exercise partner) and I went home and did an exercise ball workout from a DVD that came with an exercise ball that she recently purchased. It was fine, but it didn't really get me sweating, though she was having a really hard time with it. I just didn't feel like I got that great of a workout with it, however, I'm not sure if sweating profusely is really the point of doing the stretch/weight type exercises.
My question is, what kind of role should this type of exercise be in my weight loss program? If I were to do these things with weights, stretches, resistance (on and off the exercise ball), what else should I be doing for more...uh, cardiovascular activity and in what proportion? I.e. should I do the weights/stretches 2 days a week and then aerobic stuff 3 days a week? Or just do 20m of weights/stretches and then do my full aerobic workout 4 days a week?
I'm just trying to figure out what I should do. John's (my fiance) mom wants to do this with me, but I am concerned that will limit what I can do. Does anyone have ideas of things we can do where I can do a more intense workout than her? Like, we were doing that exercise ball DVD and it was really easy for me, but she was struggling. If I put it on the next skill level, then she'll be lost. She's 65, and I'm 22 and though I weigh more than her, I have noticed that I am much more flexible, stronger and have a longer endurance for things, as you might expect from two people at such different ages. I fear we may not really be that compatible for exercise partners. On the other hand I really want to make sure she does it because she's having some health problems with diabetes, her heart, etc, and exercising regularly every week will help her immensely.
