It may not be every runner’s favourite activity, but a solid strength and conditioning routine is something we all need in our training toolkit. Not only can time in the gym help prevent injury, but studies also show that building strength can have a direct impact on your speed and endurance.
Of course, that’s something Josh Kerr – middle-distance runner and new men’s mile world record holder – knows well. At the weekend, the Scot wrote his name into the history books by running a 3:42.66 mile at the London Diamond League.
A recent YouTube video from Track All Access also gave us an insight into the strength training routine that helped him get there.
The video shows Kerr training alongside his teammates at Brooks Beasts Track Club in Albuquerque, New Mexico, as they work through a series of 10 targeted movements.
As well as the expected leg-strengthening exercises, the workout includes movements designed to improve core stability and develop explosive power – both of which are essential for runners, particularly those racing over shorter distances like Kerr.

- Lower your chest towards the floor, allowing your elbows to track at roughly 45 degrees.
- Press explosively back to the top.
- Lift your right hand from the floor and rotate your torso, reaching towards the ceiling. Follow your fingertips with your eyes.
