I have started a crossfit exercise class. I have been doing it for about a month. Started very low weight, (like a 5 foot 1" PVC pipe filled with sand light) to learn good form and mechanics so I do not hurt myself and then started increasing weight. I am still not lifting a lot of weight, but lifting more each week. I am 45 years old. I started the program at 200lbs and weighed myself last weekend and I was 181. I am sleeping better, I have more energy, have more strength and flexibility than I have had in 20 years. I think other people are starting to notice a change in my appearance because they tell me that I am looking good lately. I had to do something because I was headed down the road to a heart attack at a young age like my father. I will keep doing it because I feel better and look better.
