Are you a woman over 40? Do you look for exercises for women over 40? If you want to lose weight permanently, you need to look for the right exercise and make sure you do it correctly. Often I hear from women over 40, "I watch what I eat, I exercise regularly, but I do not lose weight". To avoid this situation, you need to get the right kind of exercise.
You need to do the right mix of physical activity. There should be three components: Cardio training, strength training and flexibility training.
Cardio training can be done in a wide variety of ways- choose the one you like most. Bicycling is great, or jogging or swimming. You can use exercise equipment too, for example a treadmill. There is a common mistake in cardio training. People do "steady state" cardio training and keep the intensity at the same level throughout their exercise. This is highly inefficient. Go for short bursts of high intensity- 30 seconds are sufficient. Then catch your breath again in the next 2-3 minutes. Repeat this throughout your cardio workout.
For strength training you need not much, often 2 pairs of dumbbell with adjustable weights are all you need. Watch out for proper form when doing these exercises. This will not only prevent injuries, it will make sure you get the most out of your workout. Don't fear you'll become bulky- this is very hard for women and you would have to train a lot.
Flexibility training counterbalances the effects of strength training. In strength training we flex our muscles; in flexibility training we lengthen the muscles. In addition, flexibility training helps with the results of aging: after 40 our bodies tend to become tight.
