If you've experienced arm pump during a race, what has happened?
Answer Your arms have become almost immovable during a race.
Arm pump is something that typically happens during the last part of a moto race and involves a rider's arms becoming almost totally immovable. Some drivers say it's like their arms are stuck in concrete, and it can be difficult to use your hands to grip as well.
