Excellent interview with the "elderly" 60 year old lifter with a resting heart rate of 60 and systolic BP of < 120.
He talked about an interesting concept of "bus bench" versus "park bench" workouts. You can listen specifically about this concept at the 31:14 mark
From his article on T-Nation (I used to frequent this site once upon a time):
Or how Tony Gentilcore paraphrases bus bench stuff (allowing the general population to relate):
I think that "park bench" anything (maintaining consistency as priority) most of the year and "bus bench" a few short periods a year (going full balls to the wall) is a good way to keep yourself sane and have sustainable success.
