This structured climbing class will involve progressing through 4 phases of a climb, gradually increasing in length and then decreasing in a pyramid fashion. In total there are 9 sets, each consisting of 4 phases. For each set, the duration of each phase will increase by 30 seconds (except phase 4 which always remains 30 seconds) up to 2 minutes 30 seconds. Then you will descend back down all the way to 30 seconds phases in the final set. There is no 'recvoery' periods although each phase 1 allows for the heart rate to lower sufficiently for the next set.
Phase 1: Seated climb. Find a resistance that brings intensity to 10-15 beats below threshold (zone 3) at a cadence of 65-75rpm.
Phase 2: Seated climb contunues, but this time we add enough resistance to feel the hill get steeper - heart rate increase by a few beats.
Phase 3: Add enough resistance so you need to stand up for the climb. HR increases slightly again to just below threshold.
Phase 4: This phase is always 30 seconds. Whilest standing we will add even more resistance and push for 30 seconds. You should reach threshold and some will go over!
