To play music, you need technique. To have good technique, you need to be in somewhat good shape. You need flexible fingers to play guitar, bass or piano so you need to keep your hands in good shape! You need good general physique to drum and exercising is a great way to be a better drummer. Many drummers can smoke and drink without it affecting their drumming. For me, I love yoga and think that practicing yoga is better for my well being and drumming than smoking! Try yoga before Newports.
