WOD or....."Workout of the day" this is where you come to find out what your coaches have in store for you. Unlike old school workouts there is a purpose and accountability for all WOD's. Some are numbered, some are timed and some are weighted. Crossfit doesn't get easier you just get better and go higher, get stronger and go faster.
Don't let the WOD scare you Crossfit is universally scalable so your trainers may tweak your time or your weights we will get better together one WOD at a time.
