Judith, Nuts, acocados & olive oil are "good" fats. A small amount, since they are high in calories, are ok to have.Stay away from the trans fats and saturated fats (animal & dairy). As for the specific weight traing excercises, these would be a good start:: All are 3 sets to 10-12 reps with 1 warm-up set (8 reps). The weight should be enough so you cannot do more than 12 reps. Ask a trainer to show you how to properly do these. Day 1: Biceps-Seated dumbell curls, palms up. Seated dumbell curls, palms in. Triceps-Standing rope pull-downs. Skull crushers (lay down on flat bench with barbell). Abs-Crunches. Reverse crunches-both on incline bench. Shoulders-Seated dumbell presses. Seated dumbell lateral raises. Day 2: Back-Seated back extensions. Seated cable pull-downs. Rows. Chest-Bench presses. Flys. Day 3 Legs-Squats. Lunges. Seated leg extensions. Leg curls. Calf raises (seated or standing). Note: if you have the time you can do 20 minutes of cardio AFTER the weghts. If not, do 45 minutes on the off-days. After 8 weeks of the above you can add 1 new excercise to each muscle group. By then you will also have to add more weight to each excercise, since it will become easier to do 12 reps. The diet is at least 50% of the program so watch your total calorie consumption. About 10 calories for each lb. you want to be at. If you want to be at, say, 130 lbs, kepp your calories at approx 1,300. Don't forge to drink plenty of water throughout the day.
