There are several who are, but I'm not one of them. It takes a while to adapt (switch your body from burning carbs for energy to burning fat for energy), so that first week or so, you likely need to take it easier... There may be more folks on the Low Carbers Daily forum than here, at first... If you don't get some better answers, shoot my a PM and I'll look up some links for you.

I lift and do HIIT workouts several times a week. Have absolutely no problems with either on a keto w.o.e.
When I was first adapting, I did take a short break from it as I got the keto flu quite badly, but it was very transient and easily treated. I often exercise later in the day, and keto helps me to still have heaps of energy to achieve gains in exercise which I never had when eating a lot of carbs.

I lift and have not had any issues past the first couple of weeks. My work outs are not intense by most people's standards but for me they are. I don't know if that's why I haven't had any issues lifting while in keto.
