Post-Exercise Nutrition

Building a House Out of Legos®

Some of you have heard me say that if you want to build a house out of Legos but you don't have any Legos, you're going to have a tough time building that house.

Your muscles work much the same way.

Strength training stimulates your muscles to adapt and grow stronger. Protein supplies the amino acids your body uses to repair and build muscle tissue.

And that's where post-workout nutrition comes in.

Three Simple Post-Workout Recovery Drinks

For most adults, 20–40 grams of protein after strength training is a good target. Older adults, larger individuals, and those working to build muscle may benefit from the higher end of that range.

Here are three (plus a bonus) easy ways to get it done.

1. Chocolate Milk for Grown-Ups

• 1 scoop chocolate whey protein powder (25–30 grams of protein)
• 12 ounces milk or fortified soy milk
• Pinch of salt, if desired
• Shake and drink.

Approximately 35–42 grams of protein, depending on your ingredients.

No blender, no banana, no dishes. Just chocolate milk with considerably more muscle-building potential.

2. The Post-Workout Iced Latte

• 1 scoop vanilla whey protein powder (25–30 grams of protein)
• 8 ounces milk
• 4–6 ounces chilled coffee or decaf
• Ice and cinnamon, if desired

Mix the powder with the milk first, then add coffee and ice.

Approximately 33–38 grams of protein.

Coffee-shop flavor without the coffee-shop price. Use decaf if caffeine might interfere with your sleep.

3. Mark's Strawberry-Banana Smoothie

• 1 cup plain Greek yogurt
• ½ cup frozen strawberries
• ½ banana (without the peel)
• ½ scoop vanilla protein powder
• Water or milk to thin
• Blend until smooth.

Approximately 30–40 grams of protein, depending on your ingredients.

A little more effort, a little more cleanup, and a very respectable breakfast or post-workout snack.

4. Bonus Option: The Emergency Protein Kit

For the ultimate in portability, keep a dry shaker bottle with a premeasured serving of protein powder in your gym bag. Add water, shake, and drink. No refrigeration required until mixed.

Why Protein Matters

Strength training stimulates muscle protein synthesis, the process your body uses to build and repair muscle tissue.

Eating protein supplies the amino acids needed for that process. Over time, this combination helps increase strength, preserve muscle mass, and support healthy aging.

Your total daily protein intake matters most. Spreading that protein across several meals gives your muscles regular opportunities to use it.

What About Carbohydrates?

Your muscles store carbohydrates as glycogen, which helps fuel exercise. Training uses some of those stores, and eating carbohydrates helps replenish them.

How much you need depends on how hard and how long you've exercised.

A typical strength training session generally requires less carbohydrate replenishment than a long bike ride, intense endurance workout, or multiple training sessions in one day.

Fruit, potatoes, rice, oats, and other carbohydrate-rich foods work beautifully. Sugar and maple syrup also replenish glycogen, which is why they  occasionally find their way into my shaker bottle.

When Should You Eat?

Ideally, have some protein within a couple of hours after training.

The old advice about a narrow 30- or 45-minute recovery window was more rigid than the research supports. Your muscles remain responsive to protein for many hours after exercise.

If you've eaten a protein-rich meal shortly before training, there's even less urgency.

Eat enough protein throughout the day, distribute it across your meals, and make sure you're getting some around your workouts.

Recovery Drinks vs. Real Food

We like protein shakes because they're convenient, easy to digest, and require almost no preparation.

But regular food works just as well.

Greek yogurt and fruit, eggs and toast, chicken and rice, or a turkey sandwich can all provide excellent post-workout nutrition.

Choose whatever works best for your appetite, schedule, and nutritional needs.

What Else Helps Recovery?

A few other things deserve attention:

• Water: Replace the fluids you lose during exercise, especially when you're sweating heavily.
• Electrolytes: Sodium and other electrolytes help maintain fluid balance. They're particularly useful during prolonged exercise, heavy sweating, or training in the heat.
• Fruits and vegetables: Provide vitamins, minerals, and other nutrients that support general health and recovery.
• Healthy fats: Important for overall nutrition, including hormone production and cellular health.
• Sleep: Your body does a remarkable amount of repair and adaptation while you're sleeping.

And for those wondering about BCAAs, a quality protein source already provides the essential amino acids your muscles need. Additional BCAA supplements generally offer little benefit when you're consuming adequate complete protein.

The Bottom Line

Training creates the stimulus. Nutrition and recovery help your body respond.

Eat enough protein, consume carbohydrates according to your activity level, stay hydrated, and get some sleep.

Use one of our recovery drink recipes, eat a proper meal, or develop a system that works for you.

There are as many opinions about nutrition as there are people on Earth, and plenty of legitimate reasons to eat differently.

If you've already got a system that's working well, terrific. If you haven't, this is a pretty good place to start.

Now go build something out of Legos.

Addendum: How to Choose a Good Protein Powder

Walk into Costco and you'll find enormous containers of protein powder promising stronger muscles, faster recovery, and all sorts of wonderful things.

Some are excellent. Others are perfectly adequate. And some are considerably better at marketing than nutrition.

Here's what we look for.

Whey vs. Plant Protein

Whey protein comes from milk and is particularly effective for supporting muscle growth because it contains all nine essential amino acids, including plenty of leucine, an amino acid that helps stimulate muscle protein synthesis.

Whey isolate contains less lactose than whey concentrate, making it a good option for people who have trouble digesting dairy.

Plant proteins, including pea, soy, and blended products, can also support muscle growth. Some provide less leucine per serving, so a slightly larger serving may be helpful.

For most of our members, we prefer whey. Those who avoid dairy or prefer plant-based diets have plenty of good options, too.

Our Three Costco Favorites

Ascent 100% Whey Protein

Our favorite overall.

• 25 grams of protein per serving
• Approximately 2.7 grams of leucine
• No artificial flavors or sweeteners
• Informed Sport third-party certification
• Made by a Colorado-based company

Ascent is owned by Leprino Foods, headquartered just down the road from Vitruvian Fitness. Leprino has decades of experience producing dairy ingredients, including whey protein.

We like the protein quality, independent certification, and relatively simple ingredients. And it's nice to support a local company.

Optimum Nutrition Gold Standard 100% Whey

Another excellent choice.

• 24 grams of protein per serving
• Whey isolate and other whey proteins
• Informed Choice certification
• Widely available and generally competitively priced

Optimum Nutrition has been around for decades and has a strong reputation. Some flavors contain artificial sweeteners, which may matter to people who prefer to avoid them.

From a muscle-building perspective, we'd be perfectly happy with either Optimum Nutrition or Ascent.

Orgain Organic Plant-Based Protein

A good option for those avoiding dairy.

• Typically 21 grams of protein per serving
• Plant-based protein sources, including pea and brown rice
• Organic and vegan options
• Widely available at Costco

Orgain offers a convenient alternative for people who prefer plant proteins. Depending on the formula, a larger serving may be useful to provide sufficient essential amino acids for muscle protein synthesis.

Check the specific product label, as Orgain makes several different formulations.

What Makes One Protein Powder Better Than Another?

1. Protein Quality

Look for a complete protein with a good balance of essential amino acids. Whey is particularly rich in leucine. A serving containing roughly 2–3 grams of leucine is a useful target, although individual requirements vary.

2. Independent Testing

Protein supplements don't require FDA approval before entering the market. We prefer products carrying certifications such as NSF Certified for Sport, Informed Sport, or Informed Choice.

These programs provide independent verification of certain quality standards, including screening for substances prohibited in sport. Check that the certification applies to the specific product you're buying.

3. Heavy Metals

Some protein powders contain measurable amounts of lead, cadmium, arsenic, or other heavy metals.

A 2025 Consumer Reports investigation found substantial differences among popular products, with several exceeding its conservative daily threshold for lead.

Plant-based products sometimes contain higher concentrations because plants can absorb metals from soil. However, contamination varies by product, and independently tested plant proteins can also perform well.

Look for manufacturers willing to share independent contaminant-testing results. Sports certifications are useful, but they don't necessarily establish that a product has especially low heavy-metal levels.

4. Ingredients

We like relatively simple ingredient lists, but don't get too distracted by marketing language.

Terms like grass-fed, native whey, cold-processed, and natural may describe genuine differences in sourcing or manufacturing. They don't automatically mean the product will build more muscle.

Some products contain artificial sweeteners, gums, or flavorings. Your taste preferences, digestion, and dietary needs can help determine which ingredients matter to you.

5. Price

Compare products based on their cost per 25 grams of actual protein, rather than the size of the container or the weight of each scoop. A larger, more expensive container isn't necessarily a better value.

And remember, protein powder is simply a convenient way to supplement your diet. Chicken, fish, dairy, eggs, tofu, and other protein-rich foods do the same job.

Our Recommendation

For most Vitruvian members, Ascent and Optimum Nutrition are both excellent choices. We lean toward Ascent because of its ingredients, independent certification, and Colorado roots.

Orgain is a reasonable alternative for members who prefer plant-based protein.

Whichever brand you choose, focus on getting enough protein throughout the day. A good powder can help, especially when life gets busy.

And if your current approach is working well, there's probably no reason to change it.
