This week use Tuesday and Thursday as active recovery days. This would be a long bike ride, swim, row or run. Something that takes 20-30 minutes. My preference would be something that you can keep a constant pace for the whole period. I would probably do a 5k row or run. This allows you to find a rhythm and just switch off.
This will be a nice change of pace and allow you to hit the the agility and speed work of the off season with gusto. Take your breaks, the off season is going to be hard.
