So these ladies and gents are exercising underground in the Metro tunnel.
They have grabbed the banister underneath and are doing pullups.
However, the tunnels are really ick!
Often a sheltering place for the unfortunate, homeless, and sick trying to get out with their belongings from the cold or rainy weather.
And the smell of urine is not uncommon even with the CCTV cameras at either end,
Nice to workout and toughen up, but this is more than a share of morning wash up or hand sanitizer can deal with. ;-)
