Quality of life is something that we all crave. And for each of us, the definition of what a quality life is will be different, but most will agree that health is one of the top contributors. In regards to health, exercise is one of the key factors that we can control. For many of us who are fortunate enough to have the resources, access and ability to exercise, the benefits to quality of life are well researched and documented including reducing depression [1], improving pregnancy outcomes [2], reducing all-cause mortality [3], as well as reducing fall risk [4] and increasing cognitive function [5] in older populations.
Sometimes, however, an increase in exercise duration, frequency or intensity can lead to pain, burn-out or injury. In order for your body to adapt to exercise in a positive way, it needs the support of the four R’s: Rehydrate, Refuel, Rest and Rebuild.
Rehydrate – Fluid loss during exercise has several variables including the ambient temperature, intensity of training, and individual sweating rate, as well as other variables. The American College of Sports Medicine suggests weighing yourself pre- and post-exercise to get an idea of how much water is being lost, and for each pound lost to drink 16-20 ounces of liquid gradualy over the next few hours [6]. Don’t drink it all at once and be sure to check this protocol with your doctor to make sure it works with your specific situation.
Refuel – Take into account your goals for exercising your body. Are you wanting to add lean muscle? Decrease body fat? Just keep moving? All of these options will have different post-exercise refueling needs but the base line intention should always be to provide the body with the resources to repair any damage from training stress. If you have ever had remodeling done on a house because you wanted to improve it, you wouldn’t just stop after the demolition. You bring in new materials to create the changes you envisioned. And, like the remodling analogy, the higher the quality of materials – the higher the quality of results. The Academy of Nutrition and Dietetics recommends refueling within 60 minutes after training [7].
Rest – This is one of the easiest to skip for a lot of us but it is as important as the exercising if you want to improve your health. The amount of rest depends on, again, your specific factors including the magnitude of change in activity (longer duration, increased resistance or intensity during training), the amount of general stress in your life, the amount and quality of your sleep and your general metabolism, to name a few. The goal for this one is to collaborate with your body. It loves to be challenged and will rise to the occasion as long as the challenge is appropriate for where it is starting from and you give it time to process the challenge and make use of the hydration and nutrition that you gave it in the previous two steps.
Rebuild – This is where the growth happens! You have shown up for yourself. You have put in the effort. These four steps are your tools to support your goals. Without these critical tools, a workout routine can lead to frustration, burnout, pain and an increased risk of injury, but by including the hydration, nutrition and rest, your body is then able to do what it does best – adapt! Trust your body!
Now go push yourself! But not too much. ;)
