Your workout doesn’t end when you hit the showers, recovery time and nutrients are important factors to help you grow. Your workout is putting stress on your body, and fatiguing your muscles. Post workout, you want to replenish all the energy you used. You will also need nutrients to help your body repair any damage that was done to it during your workout. The two main nutrients you want to consume after a workout are carbohydrates and protein.
Carbohydrates are what you use to fuel your body, so during a workout you deplete your carbohydrate storage. The amount of carbohydrates you need to refuel depend on the intensity of your workout. The general recommendation is to consume 30g of carbohydrates per hour of exercise immediately following your workout. If you are doing an intense or long endurance session, you can get more specific with the amount, 0.6-1.0g of carbohydrates for each kilogram of your body mass. After an intense weight lifting workout, with muscle growth in mind, 1g of carbohydrates for each kilogram of your body mass is a good guideline.
Protein stimulates muscle growth and repair, which is important after an intense workout that damages your muscles. Again, the amount of protein will vary depending on the intensity of your workout. In general, 15g of protein per hour of exercise will be all you need. For a more intense or long endurance workout, aim for 1g of protein per 3g of carbohydrates. If muscle building is your goal, aim for 20-30g of protein.
The easiest way to replenish these nutrients immediately after a workout is using a shake. After drinking the shake, plan to eat a regular meal within two hours. If your primary goal is weight loss, then you can skip the shake, to maintain your planned caloric deficit, and just eat a regular meal within two hours after your workout.
One more important thing to consume post workout is water! You want to drink enough to replenish the water you lost from sweating. If you are looking for exact numbers, weigh yourself before and after your workout; the weight lost is the amount of water you want to drink. If you don’t want to go through the steps of constantly weighing yourself, just keep drinking water. Water is good for you, so don’t worry too much about figuring out an exact amount.
