5. Biking A short study conducted in 2006 found that after eight weeks of interval training workouts subjects could bicycle twice as long as they could before the study, while maintaining the same pace. So break out the old stationary or outdoor bike and do some intervals!
6. Train at Home Not having a gym membership is clearly no excuse! You don’t need any equipment to get an effective interval training workout done. High knees, fast feet, jump rope, or any plyometric exercise like jumping lunges work great to get your heart rate up fast.
