Johnny Nelson is back in action, but this time it’s not in the ring. The former world champion steps into UBX Hammersmith to take on a full 12 rounds of circuit training, pushing his fitness, endurance and mental strength to the limit. Teamed up with Richard Maynard, Johnny goes through a relentless mix of pad work, heavy bags, weights, pull-ups and more, in a session that doesn’t let up from start to finish. Led by trainers Kain Tippett-Wilson and Gabriele, this is a proper test of what it takes to go the distance, even for a former champion. Can Johnny still go 12 rounds, or will the UBX circuit break him? Let us know in the comments, could you last all 12 rounds?
