Energetic pop music blasted from speakers at a modern climbing gym in Kyiv as Ukrainian veterans stood at the foot of the wall doing burpees and crab walks, resistance bands looped around their prosthetic legs.

The men were wounded at the front fighting off the Russian invasion, which has now dragged into its fifth year and is seeing casualties mount every day.

Tens of thousands of wounded veterans are readjusting to civilian life, finding solace in the host of activities and communities popping up to cater to their growing numbers.
