Exhausted After Working Out?

Why post-workout fatigue isn’t (always) a fitness problem.

If you’re in the gym because you love how capable and powerful it makes you feel, but when you return home after a killer workout, you hit a wall, wondering if you should just call it a day and curl up on the couch for a nap… We need to talk!

The Capacity Bucket Model

To understand why you’re crashing, I want you to think about a bucket. 

Every person’s capacity can be represented as a bucket. 

This bucket “fills” with stressors, good and bad. If we keep the life and training loads within the capacity of the bucket, we are usually good!

Sometimes we might even overfill the bucket a little bit, and that’s usually fine, but where we can get into trouble:

• The bucket “shrinks” or springs a leak 

• Consistently overflowing the bucket (exceeding capacity)

We think training is what gets us stronger, but it’s actually more about the process of recovery.

How strong you get is determined by how well you recover. 

When recovery falls behind, you body may start to tell you with:

• Feeling exhausted after workouts

• Constant soreness

• Brain fog

• Difficulty focusing, especially on technique

• Low motivation to train

• Feeling like fitness is taking more from your life than it’s giving

This is not a failure or a lack of fitness– it’s feedback. 

So is Nutrition the Problem?

Maybe.

Not every case of fatigue is caused by nutrition. 

Sometimes life stress is crowding out your bucket or sleep suffers. 

Smart, progressive training loads also play a huge role in managing recovery (first day back, feeling good, and overshooting? Yeah, been there!)

But nutrition is one of the most common pieces of the puzzle that often gets overlooked. 

The challenge is that most people focus on what’s happening after the workout while missing the bigger picture.

I also find in practice that a few tweaks have massive carryover, so you don’t have to go on a wild goose chase trying to fix fatigue with lab testing and supplements. 

Ready to start patching those leaks?

The good news is that you don’t have to be elite or drop hundreds to get more in tune with your recovery. Check out this free 20 minute mini-training to help you decode post workout fatigue here!
