Hi Marinette:
I am a fellow thin woman in her forties. I recently had to take 6 months away from exercise and lost 8 pounds during that time. I started working out again a month ago and my weight is going up and the muscle is coming back on.
Yes, it is possible for you too!
I notice change in my body and fitness levels pretty immediately. You will too. It is never too late. Start tomorrow! Cathe workouts can indeed help, as can those by any instructor really.
Select a variety of workouts to help you improve your cardiovascular fitness (cardio workouts: step, circuits, kickboxing, swimming, running, powerwalking, etc) and others to help you gain some muscle and definition. You can use DVDs to improve cardiovascular fitness but you should consider doing a couple of different activities so that you develop all your lower body muscles effectively and you don't necessarily need DVDs for all activities. Just head out and powerwalk or run to start with. Within a month you'll have gained a lot. Your heart and lungs will thank you.
To gain some muscle you want workouts that focus more on strength rather than endurance. You will gain some muscle initially from doing endurance workouts that use lighter weights for over 12 reps per exercise/set. Eventually though you will want to move up to strength workouts that use heavier weights and involve lesser reps (6-12 per set, per exercise).
Cathe's Slow & Heavy DVD is a series that can really help thinner people/hard gainers to develop muscle. It is an excellent place to start as the slower pace really gives you the time you need to make sure your form is perfect. Cathe's 4 Day Split is another excellent choice since it includes full weight training routines with heavy weights for the whole body and also 4 different cardio workouts, so there's a lot of variety. The new Low Impact Series might also be a good place to start as it includes a variety of cardio, weight training, circuits, yoga, barre work and you can really grow with this series too. You can check out clips from all these different DVDs here on Cathe's website.
Don't worry about not being able to complete all the reps of an exercise, or needing much lighter weights than Cathe uses: this happens to us all! Start where you feel challenged and you will grow if you work consistently.
Thin women who have had to take a break from exercise can get healthy, build muscle and not lose weight while they improve their fitness. Eat healthily, increase your calorie intake by about 300 calories per day to start with as you begin your fitness journey (lean proteins, whole grains, veg and fruit) and make sure you give your muscles the rest they need so they can repair themselves and grow!

Hope some of this helps,
