get moving is the key.

Some of my best friends are personal trainers and they say the same thing. When you tell people just moving essentially gives you what they refer to as "free exercise". The kind that doesn't make people feel like they have to get up off the couch, change their clothes, go to the gym, get on the treadmill, lift their weights, etc.

Just walking around the block. Just walking up a few flights of stairs. Just doing something that doesn't feel like you have to have a huge investment is sometimes the best way to start - then transition into more structured stuff like wight lifting or running or anything else. And you still get the benefits for almost nothing. Walk a few flights of stairs and your legs start to burn, your lungs open up, you increase your blood flow, and you release endorphins. And it didn't cost anything if you can just include it in your day-to-day activities.

Not sure how many times I make extra trips to my basement just to get in a few more stairs. lol
