Yeah I am in Cork, havent looked at chartbusters but a lot of the salons do them if they have stand-up tanning beds.
Lyn,
you wont fall off, there are handles but its weird, cos its doesnt really knock you off balance. I think the point is you are using your muscles sub-consciously to stabilise and this works muscles gently to tone them.
I am still not convinced but as I said before its 10 mins of peace a day and normally the booth is still v.warm from the previous sunbed user. Going for session 3 today. Going daily until next Wednesday, then away for 5 days.
