Silly question really, I guess we all want to be toned and have good shape and the good news is it with a good weight training programme you can, and it does not mean spending hours at the gym.
Weight training is the key to strengthening your skeletal muscles, these are the muscles that provide movement and sit under the skin and can be seen. As I mentioned in the previous e-mail, it is very hard to build muscle and I know many females shy away from weights as they do not want to increase muscle size.
The truth is by lifting relatively heavy weights you will put your muscles under stress. The body will adapt to this by increasing the strength and tone of the muscle, providing the programme is performed consistently, is hard enough to cause adaption and the resistance is increased over time, otherwise you will find yourself going backward. The principle of reversibility!
My advice is to have your programme checked on a regular basis to make sure your balance of exercises is correct, that they are performed correctly and they are hard enough.
If you're not going forward you're going backwards.
