Advice before starting a 14 day juice feast

Hey fellas......just wanted to ask what activity you suggest while Juice feasting? is a light walk in the park for 30mins okay (also to get the sun exposure)? I will then come home and do a 45 min infrared sauna (domes, not cabin saunas)....I find this sauna super relaxing and it might just add to the cleanse? I sweat a bit in it so as long as I keep my minerals and fluids up I should be ok?

Ps I tested the pine pollen powder that came in the mail....wanted to test it before the cleanse and the first dose was like I took a powershot of caffeine.....felt great and got tingles all over my body......second & third days nothing at all! now I can see why CDs recommends to rotate the herbs....I wont take anymore herbs until after the cleanse.

thanks guys for your help :)
