Firstly I cannot take all the glory for Ben's progress as he has also worked with the legend that is working closely with him for his HYROX.
But I wanted to look deeper at Ben's achievements at the age of 49. Ben had a little break from exercise and started again recently. But he has extensive experience as a cyclist. He completed a HYROX back in January with his son but more recently he completed his second HYROX with Jack and getting a time of 102:23, a great achievement.
But what made him perform so well?
Structural adaptation creates long term changes that generally doesn't regress. These are cardiac remodelling which increases heart size, stroke volume and lower resting heart rate. We also see capillary density as well, which is generally stable.
Things that regress but can be retrained:
❌Number and size of mitochondria - responsible for aerobic energy production
❌Oxidative enzymes - responsible for how efficient you produce ATP (energy)
❌Blood changes (plasma volume) - responsible for carrying oxygen around the body.
These things can be increased with regular exercise again, supporting someone's chronic adaptations to exercise. This is why Ben performed so well once he started to exercise again.
This is why I would love to see more kids conducting exercise at a younger age. I always advise younger adult wishing to join the military to start exercises early. Do not leave it six weeks prior to testing or starting training and hope you are going to breeze it. Start early!
Ben had got Cardiff HYROX this week and for s**ts and giggles doing it twice!
Good luck to him and the team from RT Fitness who are competing this week. Enjoy the moment!
