Plank that slides, core that shakes.
Move like one rigid board, don't let your hips dip as you saw back and forth.
The Plank Body Saw isolates the Core — no passengers. That makes it a clean tool for adding targeted core volume without extra fatigue.
The Plank Body Saw primarily works the Core.
Shorten the range or use an easier variation, and stop 1 to 2 reps before failure. Reps build fast when you train just shy of your limit.
For most lifters 3 to 4 working sets. Pick the rep range that fits your goal and progress the load when the top of the range feels owned.
