Thanks so much for your fabulous feedback.
I just worked with a trainer for 3 months not circuit training – one day upper body, second day lower, third day both (not 3 days in a row) on all the machines followed by cardio. The trainer was all over the place with number of reps and weights – my choice for each machine.
I was very unhappy when the trainer (a body builder) told me I had lost muscle mass after the 3 month eval (I question the accuracy of that scale thing they use)! So I went to the owner who put me on the circuit training thing where you go around the room and start with 12 reps for the first week and go up. Preceded by cardio (bike).
I like the new routine but I was taken aback by the fact that the trainer did not look at where he might have failed and blamed it all on my not shoving food in my mouth when I get up at 6:30 AM. I cannot eat like that. My first meal is at 10 AM. I find the idea of eating something repellent when I am not hungry.
I am willing to give this a try. It is imperative that I do not lose any more muscle because I see my endocrinologist in December and I refuse to take a biophosphonate for my osteoporosis which is mild. My endocrinologist gave her overall heads up to weight bearing exercises.
Many thanks again.
Karin makes some excellent points. You could also do an all strength circuit. Alternating 2, 3, 4 exercises in a set, then moving on to another circuit of exercises. I like to do this to keep the workout moving along, to reduce boredom and to give different muscle groups a rest during the workout. There are many different ways you could do all strength circuits (rounds, ascending ladders, descending ladders, upper body/lower body group, etc).
The key is to work to the point where you can not lift another rep without reducing the weight or compromising form.
