- Escape the hot hours

The trap : as soon as the thermometer reaches 25 C, the tension rises at high speed V , the red blood cells lack oxygen and the muscles tire. As heat bypasses the dehydration signals, we often forget to drink .
Result : we quickly turn pressure cooker and we risk discomfort.
The good reflex : schedule his session before 11am or after 19h .

- Hydrate a max

The trap : 1.5 l of water a day? In summer, you have to drink double , especially when you are active. With the heat, the muscles produce more lactic acid: hello cramps and aches!
The good reflex : swallow a glass of water at room temperature every hour. During the effort, drink a few sips every ten minutes , then a drink right after.

- Do not skip the warm up

The trap : given the temperature, we tend to think that the body is already ready for the sport. Mistake: the deep muscles do not benefit from this "natural warm-up". Beware of breakdowns and other tendonitis .
The good reflex : 5 minutes of stretching before the session. Standing on one foot, bend the knee of the other leg backwards by holding the ankle 30s (ten times). Then heels on the floor, resting on a chair, lift one leg back and stretch for a maximum of 30 s (ten times). Alternate.
