@robperezfit: Most runners run on the treadmill completely flat — 0% incline. Why that’s a problem: • Running at 0% doesn’t accurately simulate outdoor running because the treadmill belt does some of the work for you. • It changes your running mechanics, making your strides slightly different than when you’re outside. • Over time, this can limit your training adaptations and leave you feeling less prepared for hills or outdoor conditions. ✅ The simple fix: set the treadmill at ~1% incline. This small adjustment: • Better mimics outdoor running effort • Engages your glutes and posterior chain more naturally • Helps you build endurance and strength safely Adding a tiny incline makes the treadmill a much more effective training tool. 💡 Pro tip: Rotate inclines for different types of runs — easy runs stay 1%, workouts can vary, and long efforts can include small hill intervals.
