After rock climbing or gym climbing of one trail, the muscle of forearm ache very much. This make my finger out of power an the next climbing. Is there any good method to eliminate ache of muscle of forearm in a short time? How to train to increase endurance of muscle of forearm?

Bengay muscle cream. It feels so great! Just put that on and it should help! : )

Your forearms bear ur body weight when u climb- so u need to make them stronger. You may do some weights on ur off days (when u r not rock climbing) to make them stronger. Eventually ur muscles wil become bulky & strong & will not hurt so much- provided u follow ur regime regularly. So will gain endurance by practice alone- l cannot think of any other shortcuts. Make sure u give a day or two of time for ur muscles to heal properly before trying again- this will actually make u stronger.
Now to help with the pain- stretch, stretch & stretch some more- yes before & absolutely must after. You can use some light weights & properly stretch all ur body muscles - not just ur forearms. This will increase blood circulation & help dissipate the lactic acid accumulation in ur muscles & joints that actually causes that ''after-exercise-numb pain''. Also drink lots of water & good nutrition- u ofcourse know this! And in a months time u will be going at it like a pro. Good luck!

Keep climbing & do dead hangs (hang from a training board until u cannot hold on any longer) from small holds on a training board - but do not over do it. You muscles r sore but that will ease after a day - stretching will help. Also, cool packs will help but l would not recommend taking an anit-inflamatory every time u climb (like Advil) - only when u r really hurting (it is bad for ur liver).

You really need to be careful with tendons, they do not recover like muscles & if u injure them they take a long time to heal - work up to it!

Good Luck

It is a build up of lactic acid in your muscles. To elevate this you need to place opposing force on the muscles. What l simply do is a stretching exercise. Place your hands palm to palm, fingers up, and press downward and outward. You should feel a stretching in your forearms and some relieving of the pain. Shaking them out after or anytime you feel tight works with the stretching.

Dont lift weights like some of these people said. l admitt, lifting weights is great to build muscle & become stronger but theres a very negative effect on rock climbing from lifting weights. You see, lifting compresses ur muscles, thats why every time u see those body builders they will have short arms & legs. Climbing on the other hand, stretches muscles which is a good thing to reach holds further away from you. Also, combining the two could cause serious injury. l agree with Taho T on doing dead hangs. He actually gave me that advice & l bought a hang board. It works great! l am climbing at a much higher level. But anyway, the best way to sovle it is to climb more & more & those muscles will eventually get used to it. Trust me, it will take a little time, but its worth it.

Good luck.

let it rest for a while.. when you climb, move with your legs.. use your arms only for balance, or if your going past 90 degrees

Listen to Tahoe, Reedman & Dave. all 3 have good advice.
It sounds like u r new to climbing, so a few tips to help:
1) legs legs legs. its all about the legs. Concentrate on pushing yourself up the wall with ur legs, not pulling yourself up the wall with ur arms. (think climbing a ladder, u dont do pull-ups when u climb a ladder, hands for balance, legs to climb the ladder)
2a) Hips in, shoulders out: Keep ur hips into the wall, while leaning ur upper body away from the wall. The will put more of ur weight on ur feet, & less on ur arms. This will also give u a better view of what is above u to grab.
2b) Keep ur arms extended: This will preserve ur bicepts for when u really need to pull into the wall. Extended arms will transfer ur weight from ur hands to ur shoulders.
3) Dont try to squeeze water from stone: If u r applying a death grip on every hold u grab, then u r wasting energy. Only grip a hold with enough pressure to keep yourself there, but no more.

Unfortunately, ur forearms r going to hurt. They control ur grip. But if u can reduce the amount of weight on ur hands by using ur legs, keeping ur hips in, & not squeezing so hard, they will last longer. However, if l am right & u r new to the sport, consider it a growing pain. no pain no gain. Every climber is forearms hurt if they r climbing at the top of their game. Shaking out, & stretching does help, but developing the muscles will allow u to climb longer. It just takes time.

Just keep working on it to build your strength, it is not lactic acid like one person said. It is your muscles rebuilding, make sure you stretch good before and after, dead hangs good for that, so you do not strain or tear the muscle.
