The standing filly press is a standing single-arm dumbbell shoulder press: you press a dumbbell from shoulder height to full overhead lockout while standing unsupported. Working one arm at a time forces the core and obliques to resist lateral bending, adding a stability demand that a two-arm press does not require. It builds shoulder and triceps strength while also training trunk control under an offset load.

Muscles Targeted

  • Primary: Anterior and lateral deltoids
  • Secondary: Triceps brachii, upper chest (clavicular pectoralis)
  • Tertiary: Core and obliques (anti-lateral-flexion stabilizers), trapezius

Starting Position

Stand with feet shoulder-width apart or slightly staggered, holding a single dumbbell at shoulder height with an overhand grip, palm facing forward and elbow bent roughly 90 degrees. Brace your core and keep your free hand resting on your hip or held out for balance.

Execution Steps

  1. Brace your core and glutes before initiating the press to keep your torso stable
  2. Press the dumbbell straight overhead, extending your elbow fully while keeping your wrist stacked over your elbow
  3. Avoid leaning away from the working arm as the weight passes your ear
  4. Lock out overhead with the dumbbell directly above your shoulder, briefly pausing at the top
  5. Lower the dumbbell under control back to shoulder height, resisting the weight on the way down
  6. Complete all reps on one side before switching arms, or alternate reps depending on your program

Form Cues

  • Keep the core braced: A tight core prevents excessive arching of the lower back as the arm extends overhead
  • Avoid side bending: Resist the urge to lean your torso away from the working side to "help" the weight up
  • Stack the joints: Wrist, elbow, and shoulder should line up vertically at lockout
  • Drive through a full range: Start from shoulder height and finish with a full elbow lockout overhead
  • Keep the ribs down: Flaring the ribcage upward indicates you are using momentum rather than shoulder strength

Common Mistakes

  • Leaning away from the load: Compensating with lateral trunk flexion reduces shoulder work and stresses the spine. Keep the torso upright and brace the core.
  • Using too much weight: Excess load forces you to lean, arch, or use leg drive. Choose a weight you can press with a controlled, vertical path.
  • Flaring the elbow out to the side at the start: This places unnecessary stress on the shoulder joint. Keep the elbow roughly under the wrist as you begin the press.
  • Not fully extending overhead: Stopping short of lockout reduces the training effect on the deltoids and triceps. Press to a full, controlled lockout.
  • Rushing the eccentric: Dropping the weight quickly on the way down skips a large portion of the muscle-building stimulus. Lower with control.

Variations

  • Standing double-arm dumbbell press: Pressing both dumbbells simultaneously removes the anti-lateral-flexion core demand
  • Seated single-arm dumbbell press: A supported variation that reduces core and stabilizer involvement
  • Half-kneeling single-arm press: Kneeling on the opposite-side knee increases core and hip stability demands
  • Single-arm kettlebell press: Using a kettlebell shifts the load path and increases the anti-rotation challenge
  • Push press: Adding leg drive allows heavier loads and shifts the exercise toward power development

Tips for Progression

  • Increase load gradually: Add small increments once you can complete all sets and reps with strict form
  • Progress from double-arm to single-arm: Master the two-arm press before isolating one side at a time
  • Add instability: Progress from a stable stance to a half-kneeling position to raise the core demand
  • Increase time under tension: Slow the eccentric phase to two or three seconds once the standard tempo feels easy

Training Notes

Program the standing filly press 1-2 times per week as part of a shoulder or upper-body push session, typically for 3-4 sets of 8-12 reps per arm. Rest 60-90 seconds between sets, and perform it after heavier bilateral pressing movements like the barbell overhead press since the unilateral load limits how much weight you can handle.
