Also working

What it is
This advanced exercise builds significant core strength using a barbell. It primarily targets your abdominal muscles, while also engaging your lower back and shoulders. You will develop impressive stability and control through your entire core.
Technique tips
- Brace your core strongly before initiating the roll.
- Keep your back flat and avoid arching or rounding.
- Inhale as you extend forward, exhale pulling back to start.
- Control the entire movement slowly, do not rush.
- Roll only as far as you can maintain perfect form.
- Your hips should remain stable, not sagging or lifting.
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.
