Wow, how did I miss this thread? HTH you have gotten a lot of great help from the membership. First I got to say girl you are hot! If you are trying to improve on that hot bod, I guess you are looking for more definition. As the Mr. said I love weightlifting and have been doing it for years. I just started from scratch all over again 3 weeks ago after 15 months forced sabbatical due to surgery to repair the ulnar nerve and in three weeks I am back to lifting the weights I was lifting 15 months ago (actually Monday I lifted more). Hammer Time and Namso gave you what I consider the best advice for us ladies.
Here the question are you looking to look like a fitness model (You are almost there now) or like a smaller size body builder?
Is important to know what you are shooting for in terms of rep and weight. Like Namso said start small and move up but if you are looking for fitness model look (is what I shooting for) then you never do less than 13 to 15 reps and slowly move your weight up, it will give you the strength without the bulk.
If you are looking for bulk (like I prefer for my legs) then 6 to 8 reps and more weight. Just remember that any fitness program is only 30% of the equation, the other 70% in nutrition.
I used to model professionally back in the 80's and 90's when they wanted models to be Svelte and statuesque not anorexic. I did bodybuilding, ballet, and ran track and field to keep my shape and stay within contractual size. I always looked good and is the body I will have again with God's help this year.
Like you, I tend to be bottom heavy I am a Latina girl we have the market on hips, but my hips go down on size fairly quickly.
Make sure to add Yoga to your work out, it will help with flexibility, strength and will keep the bulkiness under control. I have promised myself I will add my pic to the hot girls thread this year (incognito of course). You on the other hand can add your now, you are already there.
Feel free to PM with any questions, otherwise lets keep each other accounted for while we work out. I did P90X Classic for 3 weeks and got my new program in P90X3, I just started it Monday, I love it so far, tough but doable. You are starting 5x5 In February so that is awesome. My program is 90 days, God providing I do not re-injure, I will be done April 19. I am shooting to get my goals met in two rounds of it, which will have me done by my Birthday in July. I am as excited as you seem to be. By the way the first She Hulk pics is awesome too! You can alternate them for Avatars.
