Complete #67

Divide the class into 2 groups with a timer set for 5min effort and 1min recovery, repeating for 6 rounds. Push hard during the 5-minute effort and utilise the recovery period fully. Zone 1 focuses on completing the run quickly and pushing the sled with competition weight. Zone 2 involves medium weight lunges with an emphasis on attacking the ski. Zone 3 requires maintaining a steady pace while pushing limits, as it's the only round with continuous aerobic work. Zone 4 is a cluster set; focus on the negatives by lowering weights for 3 seconds and pulling back up in 1 second. Ensure a slow descent to engage the hamstrings and glutes effectively
