Most athletes skip the nervous system reset before a metcon. Two minutes of box breathing between your last warmup set and 3-2-1-go will drop your resting heart rate 6 bpm and let you start the clock from a controlled state instead of redline. Run 4-4-4-4 cadence during prep. Switch to 4-2-6-0 once the work starts. The app handles the timing so you can focus on the lift or the pull. DM me "BREATHWORK" for the exact protocol I use with hybrid athletes before threshold intervals. #crossfittraining #metconprep #breathwork #hyroxtraining #hybridathlete #workoutprep #heartratevariability #endurancetraining
