Talk to the Crossfit trainers and ask them to adjust your workout plan as per your exact fitness and health goals. You can hire the right trainer and ask him/her to modify the exercise plan so that you do not get bored with the same kind of workout. Along with exercises, you can plan a balanced diet plan to achieve your goals faster. Make sure that you eat a balanced diet to help your body get all the required nutrients. Along with Crossfit training, you can also try some other physical activities such as walking, running, swimming, etc.
