Sprint Intervals Fast Running
Sprint intervals fast running is a bodyweight cardio training method targeting the quadriceps, with secondary engagement of the hamstrings, glutes, and lower legs. It structures repeated bouts of all-out sprinting with rest intervals to maximize anaerobic power output and metabolic conditioning.

Set up the space or machine for Sprint Intervals Fast Running and begin at an easy pace.
Confirm you can control the movement and breathe comfortably before increasing intensity.

Keep the movement controlled as fatigue builds rather than chasing speed with poor position.
Reduce the pace gradually at the end instead of stopping abruptly.
