A fit body is the best asset for any trekker, as it's your own body that can help you to complete the trek. If not taken good care of, it is your body itself which will want you to return from the trek, unfinished. The task is often not easy and it requires complete discipline where the body plays a very significant role. Keeping the muscles in perfect condition is one of the most important practices of any trekker. While climbing up and descending down on the trek, almost all the body parts are utilised. Hence, keeping the muscle injuries at bay is the most important task for any trekker. However, it is not difficult and if you follow these basic routines then you will be all set for it.
Importance For Warm Up Excercise Before The Trek
Usually, simple day hikes do not require any critical planning, but if you are on a multi-day trek in the remote Himalayas, then it becomes utmostly important that your body does not give up due to physical injuries. Trekking is a strenuous activity and before starting the day's trek, it is very important that you prepare your muscles and body for it. These are called warm-up exercises and it helps prevent muscle cramps and injuries on the day's trek. It involves exercises like spot jumping, hip rotation, wrist rotation, foot rotation, hamstring stretch, quadriceps stretch, push-ups, etc. While doing the warmup exercises, do note that you should not overdo it as you are still to trek. A quick exercise for 10 - 15 minutes is enough to get going for the day. Not more.
Importance Of Cool Down Stretches After The Trek
After a tiring day's trek, it is very important that you perform cool-down exercises so that your muscles feel relaxed and release the lactic acid accumulated during the day's trek. Even if you miss the warm-up exercise, it does not affect you too much if you start the trek easily and then make it intense. However, cool-down exercises are very very important and should not be missed.
Below are a few post-trek stretches which will help you recover well and quickly after a trek and keep your muscles injury-free.
