As the Chris Gayle Academy enters its fourth year, we were invited down to Walthamstow as the group were put through their paces by strength and conditioning experts Tenax Performance.
Tenax's Connor Browne and Harry McQueen, meeting the team for the first time, got them working hard on fitness, agility and speed drills, before they finished with the yoyo test - rather them than us!
This session was the start of a closer partnership between the Academy, run by Donovan Miller, and Tenax.
The Academy, which runs in the UK and Jamaica - with further expansion on the cards - delivers access to quality education, training and personal development plans for late developing cricketers.
"Everything is going brilliantly," Miller told us. "It's amazing how time has gone quickly.
"Four years on we are doing the same things that we started out with and getting better at it!"
During the day, we spoke to a number of young people on the programme, as well as Browne - so look out for those interviews and more coverage of the Chris Gayle Academy over the coming weeks.
For now though, have a look at the images above that show just how far the programme has come since it was launched back in 2013.
