 all forms of activity, so long as they're applied appropriately, will have a benefit, okay? Appropriately, that's the key word here. If it's appropriate, all movement is good for you. However, they're not all equal. Some are better for you on a time per time comparison than others. Strength training is in another universe in terms of the type of results that you get. Nothing comes close to its ability to affect your blood sugar. Nothing comes close to its ability to affect your hormones, your metabolism in a positive way in the sense that speeding up your metabolism makes it a lot easier to live in a world with lots of food. Nothing will positively affect your mobility like strength training appropriately. Nothing will impact your body's ability to deal with stress or even sedentary lifestyle like strength training will. In other words, strength training is when you look at all the forms of exercise, as you get older, if you only had to pick one, that would be the one to pick because it's going to give you by far the most paying for your buck.
