Guys, I am 43 years old and my last visit to the doc he said "you have the body & health of an 18 year old"
Work out every day, eat very healthy, drink only warm water and herbal teas instead of coffee etc.
Eat right and pursue the healthy life. Don't let old age get you!
Whether it's 50 crunches every other day or?
keep it up and live a long and healthy life!
Trust me, you will thank yourself later!
