We started the exercise schedule last night. We do 10 push-ups, 10 sit-ups, 10 jumping-jacks and 10 squats together; and then start the cycle all over again until tired. I could only do total of 20 for each category. I figure, it was my first day and I should take it easy; will increase the repetition number each day. My goal is to reach 40 reps for each category. Hey, summer is here, we all can use a trim body in the swim suit. Will see the results after 1 month.
