? The head : always up, with the look that carries away (if you lower it, you may look like a runner, but with muscle pain in the key). Move the neck to avoid tension in the neck.

? The arms : keep them in line with the body and bend your elbows significantly to absorb shocks from potholes and to maintain the flexibility of the steering.

? Hands : place them on the top of the handlebars (ATV) to keep the neck straight and relax the neck muscles. In the hollow of the hanger, you reduce wind resistance. On the handles, you're closer to the brakes: in town, it's more cautious.

? Buttocks : raise them a few centimeters as soon as the seat becomes stiff and when you climb.

• The legs: adjust the saddle to the correct height. When the pedal is down, the leg should be a little bent. Too tight, all the effort is on the calf. His work is unbalanced compared to that of the thigh and you're tired.
