We know that exercise transforms the body, but what if we told you it also strengthens the mind? The science is clear. High-Intensity Interval Training (HIIT), running, and walking all play powerful roles in supporting long-term brain health. At Shred415, we combine all three in every class, creating a workout that is just as good for your brain as it is for your muscles.
Here’s how getting your Shred on can help you stay sharp, focused, and mentally strong.

The Brain-Boosting Power of HIIT
Shred415 classes are built around HIIT, and the mental benefits are just as impressive as the physical ones. Research shows that HIIT can:
- Increase BDNF (Brain-Derived Neurotrophic Factor)
BDNF is like fertilizer for your brain. It supports neuron growth and keeps your brain healthy and adaptable. Studies show that HIIT can significantly boost BDNF levels, supporting memory, learning, and cognitive function. - Enhance Neuroplasticity
Neuroplasticity is your brain’s ability to change, grow, and form new connections. HIIT has been shown to improve markers of neuroplasticity, helping you stay mentally sharp and improving learning and memory. - Improve Mood and Mental Resilience
Feeling stressed or mentally drained? HIIT has been shown to boost mood and reduce symptoms of anxiety and depression by increasing feel-good neurotrophic factors in the brain.
Running, Walking, and Brain Health
Shred415 isn’t just about the floor work. The treads play a huge part in delivering brain benefits, too. Whether you’re sprinting, jogging, or walking, you’re helping your brain in more ways than one.
- Walking Improves Focus and Lowers Stress
Walking has been associated with improvements in executive functions like attention and memory. Plus, it’s an excellent tool for lowering stress and anxiety, making it a simple but powerful way to support mental well-being. - Running Boosts Hippocampal Growth
The hippocampus is the part of the brain responsible for memory and learning. Long-term running has been linked to improvements in hippocampal health, helping you stay sharp as you age. - Walking Reduces Brain Aging
Prefer to walk during class? Great news. Walking has been shown to increase hippocampal volume, which helps preserve memory and cognitive function.

Why Shred415 is Good for Your Brain
Shred415 classes give you the best mix of everything your brain needs. The combination of strength training, HIIT, running, and walking creates an experience that keeps your mind engaged and your body moving in ways that boost brain health.
