BIDWB: When should an athlete build muscle?
Mostly in the off-season. In-season, the job changes.
Save this if you train, coach, or parent an athlete. ๐
๐ข These kids aren't just building muscle.
They're also growing โ taller, into adult bodies, on a timeline nobody controls.
Building strength on top of that is asking more from the same fuel tank, not less.
Practices and games spend resources.
Building tissue costs resources.
Growing costs resources.
All three pull from the same plate and the same pillow.
Off-season: build muscle, strength, power.
In-season: maintain it, fuel it, recover, don't gain it just to lose it.
If a young athlete is losing weight or getting weaker mid-season....
That's not enough food or not enough sleep, showing up as lost tissue during a season they're also supposed to be growing through.
And it doesn't stop at the body.
Calories just means energy โ and when energy is low, mood goes with it.
This is where "burnt out" comes from.
Where a kid starts resenting practice, pulling away from the team, going flat on a sport they used to love.
That's not (just) attitude.
That's a kid running on empty, still being asked to perform.
What that actually takes:
Protein at most meals, not just after practice.
Enough total food โ growing + training athletes usually need more than parents think (3 meals, 2 snacks).
Carbs around practice and game days, not just "eat healthy"
Sleep โ this is when the actual growing and adapting happens, not in the gym
Sports aren't separate from nutrition.
Height, strength, mood, third-period legs are all downstream of what went in that day.
So it's not "eat clean and hope."
It's enough food, enough protein, carbs timed around the work, and sleep to let all of it:
Muscle, height, and mindset
actually happen.
What's harder right now โ eating enough, or sleeping enough?
