There has been some good commentary about Farah and how Salazar as his coach got him set up to win gold. A key thing was strength training:
Salazar said: ‘When Mo came to me 18 months ago, he was a skinny distance runner with a great engine but no upper body. At the end of races, he would tire and his head would bob around and his arms would flail.
‘He was the weakest athlete I’d ever trained — in terms of core strength and being able to do push-ups, sit-ups and single-leg squats. He was a 90lb weakling.
‘The No 1 thing that has helped Mo is not the 110 miles a week he puts in on the road, but the seven hours a fortnight in the gym.’
