"If you want someone who will add tremendous value in your life from a strength, conditioning, and nutrition standpoint, Nikki Haimes aka Gains with Haimes is the one you should hit up. I’ve been working with Nikki for a while now and I can honestly say that if you want someone who can push you to your limits during a workout, there’s not a better person who can do it than her. I burn on average 600-700 calories during a routine 40-45 minute HIIT workout with Nikki and I’ve noticed an amazing improvement in my overall health and well-being as a result. She also has turned me on to some amazing products including The Ultimate Elixir and the Ultimate Shrooms from Live Ultimate, which I now use every day. She really does it all and I wouldn’t recommend anyone else. If you’re a winner, contact Nikki Haimes. You won’t regret it!"
