Sunday, May 31, 2009 ... a modified workout ... S ince Monday is a weights day, I couldn't do weights today and I didn't feel like going swimming or twirling away on some cardio machine, but I wanted to do something and decided on a minimum of stomach crunches and bicep curls. When I got home I realized I had done these same two exercises everyday this week. That's a first. Is it making a difference? I think so but it's hard to tell. I just keep at it knowing there is improvement even it's not immediately noticeable. Stomach Crunches on Swiss Ball: 40 reps x 9 sets with 3KG medicine ball. Bicep Curls on Swiss Ball: 7kg x 25 reps x 9 sets Posted 2009/05/31 at 20h58ET in Exercise.
