Health comes from moving your body every day. Yes, daily activities build your heart and lungs faster and more reliably than going to the gym to train.
What happens when you have a gym membership?
If you're like most people, you use it for the first month, then you decide to get up and get dressed, and having to drive somewhere is a hassle, an inconvenience, or something you just don't want to do.
You tell yourself it's too cold or freezing - or too hot and humid to leave the house. You don't like driving when it gets dark early in the morning or late at night.
Add the cost of getting out of the house and buying uncomfortable workout clothes. You probably don't wear sweats to the gym. Is that true?
Okay, so what's the alternative?
You can buy home gym equipment. But who will use it regularly? The same goes for action videos. Where is your motivation to put the video in the player, open it and actually practice?
What to do?
Exercises that work your upper and lower body at the same time do more to improve your heart and lungs – your overall endurance and vitality. Working one muscle a day is not optimal in the big picture of health. (Of course, I'm talking about general health, not fitness.)
They teach it takes discipline to sell their software. Yes, most of those programs work very well. Maybe you don't need fancy apps or hardware.
