Do stretch every day and work at it progressively. You can’t become flexible overnight. Work at the rate you are comfortable with, and then slowly increase the difficulty (length of time, length of reach or both).

Stretching not only improves appearance, lengthens muscles, and gives that lean, toned look on stage, but it also improves fitness and health. It is the ultimate for preventing injuries; in fact, at least 50% fewer overextension injuries are reported with athletes who use a regular stretching routine compared to those who don’t! Stretching is a great warm-up or cool down and improves muscular coordination, as well as prevents soreness and promotes faster recovery.

Concentrate on overall fitness and maintaining a healthy heart.
For best results, eat six times a day. Try balancing your meals 70% protein 30% carbs.

Eat a combination of lean protein and healthy carbohydrates every few hours throughout the day to speed up fat loss and maintain stable energy levels.
Eat your proteins from lean sources (Chicken, fish, boiled eggs, lean beef with all the fat drained off) and beans (lentil, lima, chile or any type of bean)

For your carbs stay away from breads, pasta and rice. They do provide energy but they are high in calories. Choose leafy vegetables, carrots, raisins, broccoli and fresh fruits. Weight train intensely, three times per week on alternating days with aerobic exercise three times per week.

Drink 10 to 20 glasses water per day NO SODA

I would recommend checking with your gynecologist as well as your arthritis specialist (if you have one) to see what they say.
