Any exercise you already do is perfect to keep on with. That said, I would advise you to approach your workout/sport with about 70-80% of the normal energy you put into it. Take it down a notch, way down. The real work here gets done with rest. If you are in training, you will need to keep it up at the minimum amount required. So as with normal exercise, when it is most beneficial to give yourself that extra “push”, in this case, it’s the opposite, lean back into less effort. The effects of the detox will most likely improve your workout/flexibility and so to give yourself the opportunity to get there, make deep rest the priority for the 7-days.

That said, it is, of course, beneficial to move the body every day.
Walking outside in fresh air, preferably in nature is extremely useful. Bringing in as much fresh oxygen to the system is so beneficial to the process. 20-40 minutes (depending on your athletic level) a day of brisk walking is deal. If you are not very physically fit, even 5-10 minutes is enough.

Don’t forget: resting is essential. ONLY when the nervous system is at rest in the restorative parasympathetic mode can the body neutralize and eliminate toxins, process and excrete digestive wastes, regenerate it’s cellular structure and restore itself completely. This is why our body shuts down every single day for about 8 hours. If you follow a regular exercise regimen, please give yourself permission to chill out a bit during the detox week.
