My transformation has come in so many ways. I had a heart bypass 2-1/2 years ago so staying healthy is my priority. I have come so far during this time with the help of Dr. Ian’s programs. I am healthy now but it does require work on my part. I am so much stronger each and every day. The workouts keep me moving and make me stronger everyday. The workout is not getting harder I am getting stronger! Eating healthy on this program has taught me so much. I love the healthy lifestyle that I have become accustomed to on this app! I have lost 7.5 pounds in 45 days and several inches. Went down a shirt and pant size. Thank you Dr. Ian and this app for helping me become stronger and healthier!
