Train Like You
Mean It.
You wouldn't skip your working sets. So why skip the fuel that makes them count? What you eat around training — and especially during injury — decides whether the work you put in actually turns into results.
Everybody at Root Strength knows the training part. Show up, put in the work, progress the load. But there's a piece that quietly makes or breaks your results — and it's the one most people wing: what you eat, especially when you're banged up.
Here's the thing nobody tells you. If you train hard enough, you're going to get dinged up eventually — a tweaked shoulder, a cranky knee, a strain that sidelines you for a couple weeks. And how you eat during those weeks decides whether you come back in two weeks or two months.
This isn't bro-science. It's what the research actually says about fueling recovery — and it applies whether you're rehabbing an injury or just trying to recover between hard sessions.
Why Recovery Burns More Fuel, Not Less
When you're hurt or coming off surgery, your body is doing two expensive jobs at once: rebuilding the damaged tissue and fighting to hold onto the muscle you've already built. Both cost energy. Both need protein. Skip the inputs and both slow down.
Look at what happens on a timeline when you stop moving:
All of that is happening while your body is cranking up its demand for healing. So the instinct to eat less "because you're not training" is exactly backwards.
The Mistake Everyone Makes
You get hurt, you stop training, and you cut your food because you're worried about getting soft. Makes sense on paper. In reality, you just pulled the fuel out from under the exact process that's trying to repair you.
If you normally eat 2,200 calories, aim for 2,400–2,500 during recovery — about a 10–15% bump, not a cut. You're feeding repair, not bulking. The small surplus goes toward healing, not your waistline.
What to Cut Back On
Protein: How Much, How Often
Protein is the whole game when it comes to recovery. Every stage of repair — from calming inflammation to rebuilding tissue — runs on amino acids. Here's the target:
Spread it out
Don't cram it into one giant dinner. You want 35–40g per meal across 4–5 meals. When you're injured, your muscles get "anabolic resistance" — basically they stop listening to protein as well — so you need a bigger dose per meal than usual to get the same rebuild signal.
Injured muscle needs more protein per meal, not less — 35–40g versus the 20–30g you'd get away with normally. This is the single most important nutrition move for coming back strong.
Best sources
Go for leucine-heavy protein — leucine is the amino acid that flips the muscle-building switch: whey, eggs, chicken, fish, Greek yogurt, and cottage cheese.
The Micronutrients That Actually Matter
Protein and calories are the big rocks, but a handful of micronutrients do real work in tissue repair. Come up short on any of these and healing drags.
The Timing Trick
Here's a low-cost move backed by real research: pair collagen with vitamin C right before you load the tissue you're trying to heal.
Mix 15–20g of collagen peptides into orange juice and drink it 30–60 minutes before you train or do your rehab work. It puts the building blocks in your bloodstream right when the loading tells your body to rebuild (Shaw et al., 2017). Cheap, easy, and it works.
What a Recovery Day Looks Like
Here's roughly 180g of protein, spread over five meals, loaded with the micronutrients above. No blender full of powder required:
- Don't cut calories. Bump them 10–15% above your normal.
- 1.5–2g protein per kg per day, across 4–5 meals at 35–40g each.
- Collagen + Vitamin C 30–60 min before training or rehab.
- Zinc, Omega-3s, Vitamin D daily for repair and inflammation.
- Ease off the alcohol — it directly blocks healing.
- Hydrate and sleep — both do more for recovery than any supplement.
Why We Care About This at Root Strength
Most gyms hand you a program and never mention food. We think that's leaving results on the table. You can train perfectly and still stall out if you're under-eating protein and running on empty — especially when you're trying to come back from an injury.
And when something does go wrong, you don't have to figure it out alone. Root Physical Therapy is on-site in the same building — our PTs can assess an injury, build your return-to-training plan, and yes, talk through the nutrition side of healing. Same roof, same team.
This is general guidance based on current research, not individualized dietary advice. If you've got specific medical or dietary needs, talk to a registered dietitian — our team can point you to one.
