The landmine row holding a wide t-handle is at-bar row variation and suitable for building the deltoids, trapezius, erector spinae, latissimus dorsi, and glutes. The wide t-handle makes the users focus on working the posterior deltoid and trapezius more so than the neutral grip and shoulder-width grips. This exercise is good for bodybuilders and weightlifters who want to build a bigger and wider back.
The variations of this type of exercise are the landmine row holding the bar, close neutral grip t-bar row, barbell bent-over row with a wide grip, wide grip t-bar row, and lat pulldown with a wide grip on the bar. One mistake to avoid while doing the landmine row holding a wide t-handle is to move your entire body while you move the bar. Users can avoid doing this by keeping their hips bent and chest over the bar during the movement.
The toughness level of this exercise is 5 out of 10 since users have to focus on keeping their bodies rigid and avoiding using momentum.
