I'm not strong enough to do Turkish Getup's on my left side. I'm doing Simple and Sinister and I've got a 70lb kettle bell that is too heavy to do TG's on my left side. But I can do a couple on my right. Should I do them on my right side or not at all? What I've been doing for a little while now is trying to just hold the bell above my head in the start position for at least 10 seconds. 

*I've actually done a TG on my left side to be exact but it was really shaky and I feel as though it's too unsafe.
