Depends if you want to go natural or not. The vast majority of women in competition use supplements to help with rapid weight loss and tone their body. Drugs such as clenbuterol, an eca stack, synthroid/cytomel, and steroid compounds such as winstrol, anavar, and trenbolone. These things are what really changes your body drastically to give you that typical fitness model look, but if used incorrectly can be harmful. Is it worth it? That's for you to decide.
To train for a fitness compo, there are a few basic things you need to follow:
- cardio twice a day (morning and evening)
- eat properly, lots of protein
- sleep a solid 8 hours per night
- proper fluids and vitamins
- weight training, one muscle group per day, heavy weight / low reps
give me your stats, and if you want some proper coaching and guidance feel free to pm me. Getting in shape for fitness is not as tough as it looks, you just have to understand the science behind it.
Good luck,
