Surprising how fit lads and chains sometimes go together…
Chains like those are usually used to make the lifted weights increase as you raise them, rather than being worm around the neck! I guess it makes them feel ‘tough’… the rest of today’s chains are indeed neck chains (was I struggling for a theme today? … you bet!) which we woujld not ordinarily recommend for training and certainly not for acrobatic work, where they catch on things with unfortunate consequences. However, today’s lads are clearly wedded (welded?) to them.
