Hi everyone! I am very new to lifting (although not fitness). I am a dressage competitor, and I love what the little bit of weight training is doing for my riding. My goal is to look like a fitness/bikini competitor (I want a great butt). That said, I am not sure where to start on diet. I do own P90x, so workout wise I thought this may be a good place to start. Any thoughts or suggestions? H: 5'5" CW: 115 Waist: 25.5 Chest: 35.5 Hips: 35.5 Body Fat %: Unknown (not sure how to measure and math really scares me!!!)
