Before doing an exercise, especially one you've never done before, be sure to find out the correct form and amount of resistance you should be using. Often times, this is best checked by watching your movements in a mirror or having a friend or partner help you. Incorrect form can lead to limited results or injury.
It is vital to start a new exercise program slowly to avoid physical injury. Most injuries typically occur by working out too much or without a properly warming up. Begin your workout by stretching to get the muscles conditioned and ready. Increase the intensity of your workout by 10 percent each week.
You can't expect to see results right away, remember that. You have to stay focused and dedicated to your plan and a big part of that is your mentality. You can't expect to have abs in 2 weeks when this is your first time trying to get into shape, it takes months to get that lean body you are searching for.
