Throwback to a #bestfriend climb! This was a fun one challenging our teamwork and coordination! Remember to include a bunch of play in your workouts and practice! Makes life and love much more enjoyable. Train hard and stay healthy over the Christmas holidays everyone!... #friendship #climb #bouldering #teamwork #climbing_is_my_passion #markham #holidays #love #laugh #play

THE PINCH The pinch grip is important as it helps with everything. Use it with any opposing edges, any groove you can find, anywhere and everywhere! Indoor rock climbing, with its protruding holds has evolved to provide you with a tonne of surface area to use your thumb! Our thumbs are strong and can really help us lock down on a hold so use your thumb wherever you can. Narrow pinches create some hyperextension into the DIPs - so places you in a half crimp type position.... Wider pinches allow for an open hand position and often force extension at the wrist. This is, in my opinion one of the best grips to train (it's my greatest weakness!) You can train your grip using a protocol of sub-failure pinch holds (<12s) followed by 2mins rest. 1 set 8s pinch hang, 2 min rest 8s pinch hang, 2 min rest 8s pinch hang, 2 min rest 8s pinch hang, 2 min rest 8s pinch hang, 2 min rest Set end - rest 5 mins Rinse and repeat 2-5 times depending of your level of experience. Remember, tendons and pulleys need to be progressively strengthened! Rule #1 of training - DONT GET INJURED! slow and steady wins the race. #gripseries #strength #stability #mobility #chiropractic #function #rehab #movement #change #medicine #calisthenics #climbing #bouldering #fitness #training #posture #toronto #markham #education #rockclimbing #crossfit #bodyweightfitness @hubclimbing @ Markham, Ontario

A little while ago I wrote up some details of every grip type. Finally getting around to posting them! OPEN HAND GRIP This grip position places a lot less stress on the finger joints and tendons. The amount of force on your A2 pulley using the the crimp grip vs. the open hand grip is over 36x! So when you climb try your best to use this type of grip wherever you can.... This position can be trained to become one of your strongest grip positions and is most effective on deep, rounded, sloper or pocket holds. Take home - Keep the angle between your distal and middle phalanx as open or large as possible! - Use the open hand grip EVERYWHERE! train with it, embrace it, become one with it. #gripseries #strength #stability #mobility #chiropractic #function #rehab #movement #change #medicine #calisthenics #climbing #bouldering #fitness #training #posture #toronto #markham #education #rockclimbing #crossfit #bodyweightfitness @hubclimbing
