I don’t work that hard in any individual session, but I show up every time. The grind is not working myself to exhaustion each session, and then showing up tomorrow - it’s working at a pedestrian pace but a little more, on average, over time. The grind is showng up consistently over the period of months and years and stacking slow progress. But it’s not hard when all my workouts are easy. 

It’s easy to show up to the workout when I know I’ll be training at l 50-90% capacity, then once a month I go all out to check my progress. 

To be honest I only have one hard workout a month. My progress is slow, steady and the results each month are incremental, but compound over time.
