Most are familiar with doing rollouts using a basic ten dollar ab wheel, but rollouts can and should at times be done with a barbell. Using an empty bar allows you to work through slightly more range of motion than an ab wheel does. The bar sits a little lower to the ground which means your body can fall flatter. This will also place the points of contact (the bar and your knees, or feet if you're doing them standing) further apart. The further the distance between these contact points, the harder your abs must work to keep your lumbo-pelvic region positioned correctly. – Drew Murphy

Try this is a small adjustment to your ab rollouts. Simply move one leg to the side. By doing so you remove half of your base, and now puts a lot of tension on the side that stays in the middle. This creates a ton of tension across the entire torso. – Michael Warren

Doing rollouts with a landmine attachment is very unique because only one end of the bar will roll while the other end remains fixed in place. This makes the bar travel in an arc, and places a lot of stretch on your distal lats and obliques. – Drew Murphy

The objective is to resist lateral flexion of the spine (side bending) and instead remain perfectly neutral while pressing the dumbbell overhead. To master this, many muscle groups will need to kick in, but expect to feel it through the obliques, upper back, and glutes. Besides being very challenging on the hips and midsection, this exercise is often more shoulder-friendly for those with overhead limitations. Its unilateral nature allows and encourages you to better focus on upwardly rotating and elevating the independently moving scapula. – Drew Murphy
