Exercise is a key component to overlap good health. Dr Greger recommends 90 minutes per day. But that is not possible for everyone. Incorporating a couple one to two mile away alks into your daily routine can make a huge difference.
I go to the rec center twice a week. I shoot baskets for 30-45 minutes, lift weights and then get 30 minutes of cardio on the elliptical.
The other days of the week I try to walk two or three times a day. My goal currently is 12,000 steps per day as tracked by my Fitbit which basically shows a general amount of movement.
Set some goals. Team up with someone. Post your daily activity on social media. You might encourage someone else. And others may encourage you to stick with it.
