Boulder Movement Tai Seng grades, explained
Boulder Movement is a Singapore bouldering chain with four gyms (Bugis, Downtown, Rochor and Tai Seng); it marked its 9th anniversary in August 2026. The Tai Seng gym, near Tai Seng MRT, has a large slab and flat-wall section, a mildly overhanging section, a steeper cave, an endurance wall and a fitness rig. The setting team puts up new problems 3 to 4 times a week, so each gym is fully reset every five weeks.
Bouldering grades
Problems are marked with star-shaped circuit tags, not single grades. Each tag colour covers two V-grades, and neighbouring circuits overlap by one grade, per the gym's own 'Grading System' chart on its routesetting page. The gym says climbers should try boulders from at least two circuits because of the overlap.
