Strength training gives your muscles a reason to become stronger.
But training is only part of the equation.
Your body also needs the nutritional building blocks necessary to repair and maintain muscle tissue—and protein plays a major role in that process.
As we get older, getting enough high-quality protein becomes increasingly important, particularly for adults who strength train.
Unfortunately, many adults pay close attention to their workouts while giving very little thought to whether they’re eating enough protein to support them.
If you’re putting in the work to become stronger, your nutrition should help support that effort.
Why Does Protein Matter?
Protein is made up of amino acids, which your body uses for numerous functions, including the maintenance and repair of muscle tissue.
Strength training creates a powerful stimulus for your muscles to adapt. Dietary protein provides amino acids that support the rebuilding process.
Think of it this way:
Strength training provides the signal. Protein provides the building materials.
You need both.
Eating more protein by itself won’t replace resistance training, and strength training doesn’t eliminate the need for adequate nutrition.
The combination is what matters.
Protein Becomes Even More Important With Age
As we age, our muscles can become somewhat less responsive to the muscle-building effects of dietary protein—a phenomenon often referred to as anabolic resistance.
This doesn’t mean older adults can’t build muscle.
They absolutely can.
It simply means that consuming adequate protein, combined with progressive resistance training, becomes increasingly important as we get older. Research and expert groups commonly recommend more than the basic adult protein RDA for healthy older adults, especially those who exercise. PubMed
How Much Protein Do Older Adults Need?
The standard adult Recommended Dietary Allowance, or RDA, for protein is 0.8 grams per kilogram of body weight per day. But the RDA is intended to cover basic requirements and may not represent an optimal target for maintaining or building muscle in an active older adult.
Expert recommendations for healthy older adults commonly begin around 1.0–1.2 grams per kilogram per day, with 1.2 g/kg or more often recommended for older adults who exercise. Research in adults 65 and older performing resistance exercise has also found benefits to lean mass within roughly the 1.2–1.6 g/kg/day range. PubMed
For an older adult who strength trains regularly, a practical target for many people is therefore approximately:
1.2–1.6 grams of protein per kilogram of body weight per day.
Here’s what that looks like:
| Body Weight | Approximate Daily Protein |
|---|---|
| 120 lb | 65–87 g |
| 140 lb | 76–102 g |
| 160 lb | 87–116 g |
| 180 lb | 98–131 g |
| 200 lb | 109–145 g |
These aren’t numbers everyone must hit exactly. Protein needs vary with body composition, total calorie intake, training, goals, health status, and other factors.
The important point is that an older adult who strength trains may benefit from more protein than they’re currently consuming.
Don’t Eat All Your Protein at Dinner
Total daily protein is important, but how you distribute it throughout the day may also be useful.
A common pattern is:
Breakfast: very little protein
Lunch: moderate protein
Dinner: a large serving of protein
Instead, consider including a meaningful source of protein at each meal.
Research on older adults frequently discusses approximately 25–30 grams of high-quality protein per meal, or roughly 0.4 g/kg per meal, as a useful target for stimulating muscle protein synthesis. PubMed
For many people, that could mean something as simple as:
Breakfast: Eggs and Greek yogurt
Lunch: Chicken, turkey, tuna, or lean beef
Dinner: Fish, chicken, lean beef, or another quality protein source
Snack: Greek yogurt, cottage cheese, or a protein shake
It doesn’t need to be complicated.
Does Protein Quality Matter?
Yes, although you don’t need to obsess over it.
High-quality proteins provide all of the essential amino acids your body needs and generally contain meaningful amounts of leucine, an essential amino acid that plays an important role in stimulating muscle protein synthesis. PubMed
Good protein sources include:
- Eggs
- Chicken and turkey
- Lean beef
- Fish
- Greek yogurt
- Cottage cheese
- Milk
- Whey protein
- Soy foods
- Combinations of plant-based proteins
Both animal and plant proteins can contribute to a high-quality diet. People relying primarily on plant sources may simply need to pay a little more attention to total protein intake and variety.
Do You Need a Protein Shake?
No.
Protein powder isn’t required to build muscle.
It’s simply a convenient food supplement.
If you can meet your protein needs through regular foods, that’s perfectly fine. But if getting enough protein is difficult because of appetite, schedule, or convenience, a protein shake can make reaching your daily target much easier.
Food first doesn’t have to mean food only.
A scoop of whey protein after training isn’t magical. It’s simply an easy way to add high-quality protein to your diet.
What About Protein Immediately After Your Workout?
You don’t need to sprint to the locker room for a protein shake the moment your workout ends.
Your total daily protein intake is more important than hitting an extremely narrow post-workout window.
That said, having a protein-containing meal or shake within a reasonable period around your workout is a simple and practical habit—especially if you haven’t eaten protein for several hours.
Consistency matters more than perfect timing.
More Protein Isn’t Automatically Better
If some protein is good, it can be tempting to assume that enormous amounts must be better.
That’s not how nutrition works.
Once you’re consuming enough protein to support your needs, continually adding more doesn’t guarantee additional muscle growth.
Protein is only one part of a well-designed diet.
You still need adequate calories, carbohydrates, healthy fats, vitamins, minerals, fluids, and overall dietary quality.
The goal isn’t to eat as much protein as possible.
The goal is to eat enough protein consistently.
HIT Fitness Coaching Tip
Instead of worrying about the perfect protein number, start by looking at your meals.
Ask yourself:
Does every meal contain a meaningful source of protein?
For many adults, simply improving protein at breakfast and lunch can make a significant difference in their total daily intake.
Then look at the bigger picture:
Am I strength training consistently?
Am I eating enough protein?
Am I progressing in my workouts?
Am I giving my body enough time to recover?
Those fundamentals matter far more than chasing the latest supplement or nutrition trend.
One Important Consideration
Protein recommendations should be individualized when certain health conditions are present. For example, some people with significant kidney disease may be advised to limit protein intake, so higher-protein recommendations aren’t appropriate for everyone. PubMed
For otherwise healthy adults, however, protein combined with progressive resistance training can be an important part of maintaining muscle and physical function as we age. Evidence suggests that additional protein can modestly improve gains in lean mass during resistance training, although results for additional strength benefits are less consistent. PubMed
Remember…
Strength training gives your body a reason to maintain and build muscle. Protein gives it the raw materials to do it.
Neither needs to be complicated.
Train consistently.
Progress appropriately.
Eat enough quality protein.
Recover.
Then repeat those habits week after week.
Build Strength From the Inside Out
At HIT Fitness, we believe successful strength training after 50 involves more than simply showing up and exercising.
It’s about creating the right combination of training, nutrition, recovery, and consistency to help you remain strong and physically capable for years to come.
You don’t need a perfect diet.
You need sustainable habits that support the work you’re doing in the gym.
