Sprint Smarter. Not Longer. 🔥
Did you know one of the first things we lose as we age is our fast-twitch muscle fibers? These powerful muscle fibers are responsible for speed, strength, power, balance, and quick reactions—and they’re essential for staying active and independent.
That is one reason we program accessory sprints 1–2 times each week in our IGNITE classes.
These aren’t long cardio sessions. They’re short, intentional bursts of maximum effort followed by full recovery. This type of training helps:
💪 Preserve and build fast-twitch muscle fibers
🔥 Increase calorie burn and metabolism
❤️ Improve cardiovascular health
⚡ Build strength, power, and endurance
🧠 Support overall brain and hormone health
The best part? You don’t have to run. We use bikes, rowers, SkiErgs, and other equipment to get the same benefits.
At Nikao Fitness, we’re not just exercising—we’re training for a stronger, healthier future.
