Alright don’t laugh but I just improved my 60m time by almost 1/2 a second after 4 months and I put it all down to increased posterior chain strength due to Westside Barbell training.
I ran 8.05 sec on dec 31st and today I ran 7.61. OK I know this is slow but I was running half-marathons this time last year.
I didn’t practice sprints at all in between, just powerlifting, so it must be due to increased leg strength, especially my hams. Really felt my hams kicking in as well, before I could feel it more in my quads.
