Because we all want to fight together, each week will have a date on which you will be able to start a new week earliest.
You will be able to pause the Transformation Project at any time if you need to. But to make the most out of it, and also to stay in the same rhythm as your fellow athletes, you should try to always follow the Training Plan weeks.
If it is hard for you to follow, you can reduce your workload in the setup of each Training Plan week.
