So, does this happen to anyone else? I have been working out every day, but it seems fairly consistent that when I hit the “7 minute mark” (or thereabouts), I hit a wall. I always want to just quit there and call it good, but I push through it and then it feels like I could basically go forever. It is so weird. Last night especially, I hit the 7 minute mark and I was shaking and felt like I might barf (I had JUST eaten dinner after a late work day followed by mandatory errands), and my legs burned. But then a few minutes after that and I find myself more relaxed and the pain recedes and then suddenly I have been going for like a half hour after the first 7 minutes felt like 2 hours. It’s so weird. Is this typical? Anyone else have a “magic number” they have to push through?
