What it is
This is a compound pushing movement performed with a barbell in a landmine setup. You will build explosive power and strength, primarily targeting your shoulders. Your chest and triceps also engage significantly during the press.
Technique tips
- Securely anchor the barbell in a landmine or corner.
- Maintain a wide, stable stance throughout the movement.
- Drive explosively upward through your hips and knees.
- Extend your elbow fully at the top of the press.
- Keep your core braced to prevent torso rotation.
- Control the weight on the eccentric return to the start.
How to track your progress
Log the weight and reps of each set. Straddly turns every set into an estimated one-rep max, so a heavier single and a strong set of eight both count as progress, and it flags a personal record the moment you beat your best.
