To join the Russian Spetnaz, one of the test is to be able to do
pullups 18 times with a 10kg weighted attached to you.
For the US secret service, they see how many times you can snatch a
24kg kettlebell in 10 minutes(trust me, your heart in this ones
pounds 10x harder than running).You can alternate arms and catch
your breath inbetween if you want.
