It’s not what you do today that counts. It’s what you do all year, day in and day out, that does. Athletically we are the sum of the work we do. As a coach, I often see people come into the gym and destroy themselves in a 2-hour suffer-fest workout, only to not come back in a week or more. Unfortunately, this type of intermittent training has little value concerning performance. I'm not saying it doesn't have any value, but instead, it's an inefficient use of your time.
