Rock climbing and bouldering are excellent for building both strength and stamina – you’ll be gripping onto the smallest holds and hauling yourself upwards, one move at a time. Despite being solo on the wall, these sports are actually quite social. Fellow climbers on the ground can offer tips, cheer you on, and celebrate your sends – making it a fun and motivating way to work out with friends. We’ve rounded up the best rock climbing and bouldering gyms in Singapore, so grab your climbing shoes and chalk – or rent them from the gyms – and make your way to the walls.
