Engine #6B

Focus on developing lactate threshold and endurance via alternating efforts. This is the second week of a 4 week progression on lactate threshold. Set for 8 minutes of work, 1 minute of rest, for 4 rounds. Divide athletes into 4 zones; designate treadmills as Zone 1 and Zone 3. Zones 1 & 3 include two threshold efforts with a lighter recovery run between. Athletes should be fully recovered before starting the next run, extending efforts from the previous week. Zones 2 & 4 require 8 minutes of alternating pacing between 25 calorie threshold and 10 calorie easy erg. Focus on technique and skill level; aim for Hyrox Race pace or slightly faster. Try to match the pace from the previous week
