You have heard it all before – exercise is great for your body. But did you know it is also one of the best things you can do for your brain?
The way I see it, exercise works like the two hands of time:
Cardio rewinds the clock, helping you recall memories and learn better.
Strength training fast-forwards time, helping you plan, focus, and make decisions for the future.
People love to debate which is better – cardio or resistance training. But here is the truth: each does something special, and balancing both is key for brain health and overall well-being. Let me break it down for you.
Cardio: The memory rewinder
1. Boosts BDNF (Brain-Derived Neurotrophic Factor)
This vital protein helps your brain grow new neurons and strengthens neural connections. It is like giving your brain an upgrade.
2. Improves memory
Cardio has been shown to enhance both short-term and long-term memory. If you do cardio before or after learning something new, it sticks better. (So, get your kids moving too!)
3. Best intensity for brain benefits
Hit at least 60% of your VO2 max to get the most BDNF boost. Use the following chart as your guide to maximize the brain benefits of your cardio routine.
Strength training: The executive navigator
1. Improves cognitive executive function
Strength training helps with planning, organizing, and decision-making. It is your brain’s operating system, keeping everything running smoothly.
2. Focus on multi-joint exercises
Moves like squats, deadlifts, and presses give you the biggest mental boost.
3. No memory boost
Unlike cardio, strength training doesn’t directly affect memory, but it sharpens your brain’s ability to set goals and achieve them.
The Great Cardio vs. Strength Training Debate
People often argue over which is better: cardio for memory or strength training for planning. But that is like arguing over whether you need your right hand or your left hand. YOU NEED BOTH!
Balance is the key. Doing both types of exercise gives you the best of both worlds. Cardio helps you remember, strength training helps you plan, doing both reduces all-cause mortality and supports overall brain and body health. Why choose when you can have it all?
So next time you are planning your workout week, remember: it is not about choosing sides, it is about balancing both for a sharper, younger, more efficient brain.
