After my kettlebell training and Girevoy Sport practice my forearms are usually what bother me most depending on what I've done. Proper forearm, wrist, and hand care is vital for a girevik's (kettlebell lifter) ability to continue training. If your grip goes then you cannot complete your sets and your workout ends. Obviously that's not the goal and so preventive mobility drills and stretches for the forearm will allow it to continue recovery ongoing.
Here's what I do to help increase my forearm mobility and a great way to make sure your forearms are fully stretched and recovering after your kettlebell training.
