In order to get good at rock climbing, you need to work on your fitness and finger strength all the time. The Rustam Climbing Bombita Hangboard lets you practice indoors. It has various edges for two and one-hand training (central, eye, higher rower & lower row edges) and a sloper surface on top.
This climbing trainer was designed by Rustam Gelmanov, who is a world cup winning climber. Its wooden grips have less friction, so you will have to work harder to maintain your grip.
