Good advice. staying injury free is key, I noticed my leg being stretched a bit the first couple days and did not push it at the time but put it a bit to rest.

The idea is indeed to brute force a standard healthy lifestyle into my subcounciousness so it fully becomes automatic after the 100 days. I did the eating for 30 days a couple years back which really changed a lot but did not fully fix everything. Next up will probably a year long 365 challenge if these 100 days are not enough to fully do the trick.
