Dima,
A challenge is that we only offer 1 Maintenance level, which is about a level 1. Therefore, switching from the Maintenance plan to any Level 0 plan feels like a big drop.
Two options, first, exactly as vesstche recommends. Second, don’t be afraid of dropping your volume. You have the ability to make the Level 0 plan as difficult as you want by increasing the intensity to the upper limit of each zone, particularly the Zone 3 and higher intervals. 8 hours a week at 50% penetration into each zone is about as hard as 5 hours a week at 95% penetration into each zone.
Volume is a combination of volume x intensity. Therefore, when the volume is low, you can increase intensity to get to a similar level of volume.
