I started working out when I was 15. I was in gym class in high school and the gym teacher had us do some arm curls and bench press. There were about ten guys in the class and I was the weakest one. I struggled with 45 lbs on bench press and did some arms curls as well. I was sore for the next 2 weeks straight. I kept looking at my arms each day and never felt that feeling of soreness before. After that, I saved for months and bought a weight set with chore money. Years later I would venture into amateur strongman contests. Everyone should workout in some capacity. Preferably weight training and cardio. The advantages: stronger in everyday activities, better lung and heart health, makes you better able to stand a difficult work day or stressful Activities, enjoyment in beating fitness goals, you are now in control of body shape and size, etc. There are many people past and present who worked out past their 90s like jack lalanne, at the age of 80 even capable of tugging boats for more than a mile swimming! At the age of 70 for example, he tugged 70 boats a length of one mile while handcuffed and shackled. Current people like Sylvester Stallone, arnold, and Chuck Norris who all in their 70s are still in crazy shape and a lot more fit and stronger than the average man. At the end of the day, one good reason to do it and perhaps the best Is to be in control of your body and prevent it from wasting away at the natural rapid rate.
