“If it’s important, do it everyday.” -Dan Gable
This quote is applicable to any endeavor. In the context of sport and training, find a way to do something everyday that is directed toward your goals. This doesn’t mean you are trying to work as hard as possible, grinding away every day; in fact, many of them should be lower-intensity days. However, there is something that can be done on nearly any day. For instance, low-intensity activity can promote restoration. So, find a way to get your heart rate up for 20-30 minutes and improve your recovery. Or perhaps roll and stretch. In the case of general training, I think that the basic movement patterns of squat, hinge, push, and pull are important basal fitness constituents. I do so with my athletes by incorporating things into warmups, cool-downs, etc. Not everything need be externally loaded or pushed to its limit.
Keep in mind also the importance of doing the work when you don’t want to. If it’s important, show up. Everyday.
