HIIT Countdown
Why This Workout Works
This descending ladder format allows you to start with longer work intervals to build muscular endurance and cardiovascular fitness, then finish with shorter, faster intervals that challenge power, speed, and mental toughness.
The exercise selection combines:
Lower-body strength (Squat Press, Lateral Squat Jump)
Upper-body pulling strength (Dead Row)
Explosive power (Plyometric Jumping Jack, Power Across the Top)
Agility and coordination (Forward Knee Freeze Agility)
Cardiovascular conditioning throughout
As the work periods decrease, your goal is to maintain intensity and movement quality while pushing your pace.
The optional running component adds an endurance challenge that makes this workout especially effective for runners and anyone looking to improve overall fitness, work capacity, and fatigue resistance.
Equipment Needed
Dumbbells, weighted bar

Coach's Tip
Don't pace yourself based on the first round. The intervals get shorter as you go, allowing you to gradually increase your effort and finish strong. Focus on maintaining good movement quality, even when fatigue sets in.
