I started training with Kristin at IronPlate studios in November for my wedding on March 29th. From the minute I walked into the studio, I loved it and Kristin. Our first consult was very thorough.  Kristin is extremely knowledgeable and encouraging.  My goal was obviously to look good in my tight fitting mermaid dress, but I really wanted to focus on toning my upper body.  Training with Kristin was amazing - she taught me a lot about my diet and how to incorporate clean eating into my everyday life.  She was also able to construct a diet plan to suite my lifestyle. Kristin and I focused heavily on weight training, since I stuck to running and spin classes during the day. I felt stronger and stronger every day and looked even better!   Kristin changed up our routines often and introduced me to new and exciting workouts every week. When the big day came I couldn’t have felt or looked better thanks to IronPlate Studios! I plan to continue working out with Kristin at IronPlate Studios so that we can work on my next goal…to become a WWE Diva!

Kristin and Caitlin have both been instrumental in helping me lose weight and tone up for my wedding this summer. The nutritional counseling program has been particularly helpful and Kristin is always willing to help answer questions, make recommendations, etc., when it comes to my diet. I always look forward to my training sessions with Kristin and Caitlin and even though I am sore for days on end afterwards, it’s in the best way possible! Highly recommend IronPlate Studios, they are the best!!
-Allie L., IronPlate Bride

I finished the Hoboken City Challenge yesterday - with walking to and from the event was roughly 5 miles and 20 obstacles. At 57 years old. Have been with Iron Plate about 15 months. Down about 12 pounds. Might not sound like a lot - but gut gone, love handles gone, "hanging chin". gone. Body transformed. And still transforming. Energy and stamina way way up. And Kristin and Liz have become great friends! So I happily recommend that you check out IronPlate – give yourself the gift of looking and feeling good and as well as being healthy!
-Shepard F., IronPlate Man

Kristin was really helpful in helping me to fine tune my diet and to help get my physique ready for my first amateur figure competition. She was always ready and willing to answer all of my questions and to give me sensible and professional advice. Not only that, but with her help I won first place in the competition and earned my Pro Card. Thanks Kristin!!
