Squats and kettlebells

We did sets of five heavy front squats, to find approximately a five-rep max. I used 50 kg for two sets and probably could have gone at least 5 kg heavier, but we stopped in order to do the “real” workout, which was:
50 kettlebell swings (I used 18 kg)
Run 400 m
40 swings
Run 400
20 swings
Time: 6:51
