At least your gym gear won't get sweaty.
Naked Yoga is a trend that was on an uptick a few years ago. Google search data suggests it may have peaked around 2013.
So in the 'New Year, New You' vein of millennial self-improvement, a New York gym is offering naked classes.
Hanson Fitness studio founder Harry Hanson said:
Our approach makes sure our members get and stay in the absolute best shape, and our new naked personal fitness sessions are no exception.
This new development brings with it a range of fitness and health benefits and allows our members to have a little cheeky fun in the process!
If you're uncomfortable training in the nude, you can wear nude-coloured underwear instead, the gym says. The first nude personal training sessions will start on 5 January, 6 pm. There will be three a week, one mixed, one male, one female.
Funnily enough, if you're a man in the UK, this is also available to you - just not at the same gym.
NKD Training has naked gym sessions in the UK, but these are for men only - 10-20 places at 4 pm on Sunday afternoons in West London.
Who knows? It might help you with your form if you can see exactly what your muscles are doing each rep?
