Discuss with your doctor the type of diet you should be on. Your doctor might need to modify a diet an exercise routine so it better suits your needs. Sometimes other medical conditions and medications can interfere with specific exercises, this is why it is best that you speak with your doctor first.
Begin losing the weight at a slow pace. If you over do your workout it is possible that you can hurt yourself. After an injury you will need to heal before you can again begin exercising. Therefore, slow and steady is best. When deciding on the best types of exercises you want to do you should consider your target area, if you have one.
Work on that area more frequently but you should also work out the rest of your body so you are burning more calories and stimulating the rest of the muscles in your body. Put together an exercise routine and keep it with your goals. Stick with what you have decided to do.
