Dumbbell Single Arm Squat Jerk

Target muscles

The quads and glutes drive the dip-and-drive and the deep squat catch. The deltoid and triceps lock the dumbbell out overhead. The trunk braces violently against the asymmetric overhead load while in deep flexion. The shoulder mobility demands of holding overhead in a deep squat are real. As advanced unilateral overhead work, this is among the most demanding lifts available.

How to perform

Setup

Stand with one dumbbell at the shoulder in a front rack. The other arm extends for balance. Trunk braced.

Execution

Dip straight down. Reverse explosively, driving the dumbbell up. As it launches, drop into a full squat — catching the dumbbell with the arm locked overhead at the bottom of a deep squat. Stand out of the squat with the dumbbell still locked overhead. Lower to the rack. Switch sides each set.

Common mistakes

• Catching with bent elbow. Lock the arm at full extension.
• Trunk leaning toward the working side. Brace continuously.
• Squatting forward instead of straight down. The squat is vertical.
• Going too heavy without the mobility for a deep squat with overhead load.
• Hyperextending the lower back at lockout. Brace.

Progressions and regressions

Regress to the split jerk (split landing instead of full squat) and the push jerk. Build the overhead squat as a separate exercise. To progress, increase load with strict form.

Programming notes

Most demanding single-arm jerk variant. 3 sets of 2 reps per side with full recovery, twice a week.
