Football is a a great way to build fast twitch muscles and cardiovascular fitness but you can also replicate this type of training in the gym.
According to me gym is better for our health........ gym gives us the greatest amount of choices in pursuing a fit lifestyle........And also football is better for our health. But gym is better than football..I like to go gym daily in the morning.
Stairs!! I thought I was the man, because I would go to the gym and do the hardest exercises on some of the machines. Then I decided to go to this place by the beach that has a long tall staircase..... Huge difference, it worked out my whole body. So I think the naturally world is a better "gym" than the gym.
