Hangboards

One of the best ways to train at home (that is, unless you have a home rock climbing gym,) is to have a hang board. The best hang boards have everything - jugs, crimps, pinches, and slopers. Some workouts on hangboard are:

• hang for a minute, move one hand every 5-10 seconds, rest for 30 secs, repeat.
• hang one minute, off 20 secs, repeat
• pull ups
• pull lock-offs
• frenchies

You can get hang boards from most climbing sport stores - ems, moosejaw, metollius, or amazon all sell hang boards.
