These intervals will have a high aerobic demand, and also put a premium on upper body pulling endurance. Being able to consistently hit big sets on the pull-up bar after a hard effort on the row will be key, and then use our fitness to maintain a strong cadence on the box jumps. Aim to minimise breaks on the pull-up bar today, so that we can work for as much of each interval as possible. Don't be shy about putting the pedal down on the rower a bit here. You will pick up where you left off each set.
