Predator Jack
Predator Jack Exercise Description
Predator Jack is a bodyweight plyometric that blends a jumping jack with a squat and an upper‑back pull. Each rep alternates from a tall, feet‑together stance with arms straight forward to a wide, athletic squat while the arms sweep apart and the shoulder blades retract. The movement emphasizes quick ground contact, soft landings, and a neutral spine to build coordination and aerobic demand. Lower‑body work is shared by the quadriceps, gluteus maximus, calves, and hip abductors/adductors as you jump in and out of the squat stance. The arm action targets the posterior deltoids, rhomboids, and middle trapezius through horizontal abduction and scapular retraction. Keep knees tracking over the mid‑feet, maintain full‑foot contact on landing, and move only as deep as you can without losing posture or alignment.

How To Do The Predator Jack Exercise
‘- Stand tall, feet together, ribs stacked over pelvis. Arms straight in front at shoulder height, palms facing each other.
– Set shoulders down and back; lightly brace your trunk.
– Jump feet out to a wide, athletic stance as you sit into a shallow–moderate squat.
– At the same time, pull elbows back past your torso, squeezing shoulder blades together (scapular retraction/horizontal abduction).
– Land softly on the midfoot, then let heels settle; knees track over toes and stay stacked over mid‑feet.
– Keep chest up and spine neutral; avoid shrugging or arching the low back.
– Drive the floor to hop feet back together as arms sweep forward to meet at chest height.
– Maintain a steady rhythm and quiet landings; reduce depth or speed if alignment or control is lost.
Predator Jack Tips
‘- Start tall with feet together and ribs stacked directly over your pelvis.
– Reach arms straight forward at shoulder height with palms facing each other before you jump.
– Set shoulders down and back and lightly brace your trunk before initiating the first rep.
– As you jump out, sit into only a shallow to moderate squat so you can maintain posture and alignment.
– Pull your elbows back past your torso and actively squeeze your shoulder blades together on each outward jump.
– Land softly on the midfoot first, then let your heels settle to the floor.
– Keep knees tracking over your toes and stacked over the mid‑feet throughout the squat.
– Keep your chest up and spine neutral, avoiding both shrugging and low‑back arching.
– Drive the floor to hop your feet back together as your arms sweep forward to meet at chest height.
– Maintain a steady rhythm with quiet landings, and reduce depth or speed if you lose alignment or control.
Predator Jack Beginner Introduction
Predator Jack is a fast, bodyweight plyometric drill that blends a jack-style jump, a partial squat, and a rowing motion for the arms. The person moves rhythmically between a tall, narrow stance with the arms reaching forward and a wider, athletic squat position as the arms open and draw back. This repeated hopping pattern creates a continuous, full‑body pulse that challenges timing, coordination, and cardiovascular endurance while keeping the movement grounded in control and alignment.
The legs, glutes, calves, and hips share the workload as the feet spring in and out of the wider stance. At the same time, the pulling action with the arms brings strong involvement from the rear shoulders, upper back, and mid‑back. The trunk stays organized to support a long, stable spine, while landings emphasize gentle impact and brief contact with the floor. Overall, the exercise highlights smooth transitions, crisp arm‑leg synchronization, and athletic posture under an increasing aerobic demand.
