High-intensity interval training (HIIT) doesn’t have to feel overwhelming. In fact, if your goal is to see results in less time, then HIIT is one of the most effective training methods you can start with.

To help you get moving, we’ve outlined three beginner-friendly HIIT workouts — one on a treadmill, one without equipment, and one on a stationary bike. Each option is designed to maximize your workout time while keeping things approachable.

Beginner Treadmill HIIT Workout

A treadmill makes HIIT both safe and efficient since you can control your speed and incline at every step. If you’re just getting started, the NordicTrack T Series 10 Treadmill is a smart choice. It has a cushioned deck to reduce joint impact and auto-adjusting features to match your pace. If you want a little more room to grow, the Commercial 1250 Treadmill offers a -3% to 12% incline range that’s perfect for progressing your HIIT over time.
