<human>: Can you give me the gist of the text in a nutshell?

In May of 2011 I decided it was time to start losing weight. Due to multiple knee surgeries when I was younger I had developed a very lethargic lifestyle and needed to makes some changes. So I subscribed to this sub and started running 3 times a week. I started small and with a goal of a 10 min mile. Slowly over the past year+ I have been adding to my running time and now run 7 miles in an hour 3 times a week and have begun adding push ups and sit ups to my workout routine (up to 70 push ups a day and 100 sit  ups). I gradually in this time went from 185+ to now a range of 135-140. During this time many people have kept me motivated with their compliments about my change in appearance and overall health, but the biggest motivator has been this sub. 
Yesterday I had to have a surgical procedure and every nurse and doctor asked me about my heart rate. It turns out my new resting rate is around 48 beats per minute when the average is 70. Once again, thank you /r/GetMotivated  for helping me keep up my new lifestyle. Remember, we are not on diets or weight loss plans, we are starting new healthier lives.
