When you exercise, you're working to support your health and
fitness goals. Fueling your body before and after workouts is just as
essential, helping to provide energy and aid recovery. What and when you eat
can make a significant difference in your performance and results.
Pre-Workout Nutrition: Balancing Carbs and Protein
Whether you’re gearing up for cardio or resistance training,
it’s beneficial to consume a balanced mix of protein and carbohydrates before
your workout. The proportions depend on the type and intensity of exercise.
Eating around an hour before starting gives your body time to digest, fueling
your workout effectively. If your exercise will be low-intensity, a smaller
snack of around 200 calories should suffice, while more intense sessions might
need up to 400–500 calories.
For cardio workouts, aim for a balance of about two-thirds
carbs and one-third protein. This provides sustained energy from the
carbohydrates while the protein helps prevent muscle breakdown. For resistance
training, a ratio closer to one-third carbs and two-thirds protein is ideal, as
it supplies the energy needed for strength while supporting muscle maintenance.
Post-Workout Nutrition: Replenish and Repair
After exercise, your body has used up glycogen, its primary
fuel, especially needed by the brain and central nervous system. If glycogen
isn’t replenished, your body may start breaking down muscle tissue to produce
energy, which is counterproductive for muscle health.
In the case of resistance training, microtears in muscle
fibers occur, prompting your body to start the repair process immediately
after. Protein is essential here, as it helps rebuild and strengthen muscles,
while carbohydrates help restore glycogen and transport protein into muscle
cells for synthesis.
Refueling After Cardio
After a cardio workout, focus mainly on high-fiber
carbohydrates to replenish energy. Options like oatmeal, brown rice, whole
wheat pasta, and high-fiber fruits are excellent sources. Aim to consume 30–50
grams of these carbohydrates within 5–10 minutes after finishing your session
to jumpstart glycogen replenishment.
Refueling After Resistance Training
For resistance workouts, a mix of protein and carbohydrates
is crucial. The protein supports muscle repair and growth, while carbs help
restore glycogen and enhance protein absorption. After resistance exercise,
wait around 30 minutes before eating to allow your muscles time to begin the
natural repair process without pulling blood flow away prematurely. This
waiting period also helps clear out waste products, setting the stage for more
efficient muscle recovery.
Key Takeaway: Fuel Smart to Maximize Your Workouts
Both pre- and post-workout meals play a vital role in your
energy levels, performance, and recovery. By timing your nutrition and choosing
a balanced intake of protein and carbs, you’ll provide your body with the
resources it needs to repair, build, and stay energized bringing you closer to
your fitness goals.
Proper hydration is just as important as food for effective workouts. Drinking water before, during, and after exercise helps prevent dehydration, which can cause fatigue and cramps, especially during longer or more intense sessions. Electrolytes may be beneficial after prolonged or high-intensity workouts to replenish lost salts and support muscle function. Additionally, consider portion sizes and avoid heavy or greasy foods before exercise, as they can lead to sluggishness and discomfort. For those aiming to build muscle, incorporating a small snack with protein every few hours can help maintain muscle synthesis. Remember, listening to your body’s needs and responding with nutritious, balanced choices will support both short-term performance and long-term fitness results.
