Medicine Ball Slam: How to Do It, Muscles Worked and Benefits
How to do a medicine ball slam properly, which muscles it works, why it builds power and conditioning, the mistakes that wreck your back and the variations worth adding.

The landmine row solves an old problem. Barbell rows build a thick back better than almost anything, and they also load your lower back hard while you hold a bent-over position for a full set, which is where a lot of people quietly go wrong. Anchor one end of the bar instead and the arc changes: the weight travels through a fixed path, stays close to your body, and you can pull heavy without spending the set fighting to keep your spine where it should be.
It has become a staple in strength programmes for good reason, and it needs almost nothing. A barbell, a corner, some plates.
This describes the single-arm version, which is the one worth learning first.
Fix the wall before you start
A loaded barbell wedged into a plasterboard corner will leave a mark, and eventually a hole. Put an old bumper plate flat against the corner, wrap the bar end in a towel, or buy a landmine sleeve for the price of a takeaway. Cheaper than filler and repainting.
It builds back thickness without punishing your lower back. This is the honest headline. Research comparing rowing variations found that the standing bent-over row produced strong, symmetrical back activation but the largest lumbar spine load of the exercises tested, while single-arm and supported variations spread the demand differently. The landmine row keeps you in a hinge you can actually hold.
It fixes side-to-side imbalances. Training one arm at a time exposes the weaker side rather than letting the stronger one quietly take over, which is what happens on every barbell row you have ever done.
It suits home gyms. No cable stack, no lat pulldown, no machine. If your kit is a barbell, plates and a rack, this gives you a heavy horizontal pull that the rest of your setup probably cannot.
It is easier on cranky shoulders. The neutral or semi-neutral hand position and the fixed arc are usually more comfortable than a wide pronated row, which matters if your shoulders have opinions. The NHS recommends strength work covering the major muscle groups on two or more days a week, and back work is the half of that most people neglect.
Rowing with the arm instead of the back. If your biceps are the only thing sore afterwards, you never retracted the shoulder blade. Think about driving the elbow behind you, not curling the bar upward.
Rotating the torso to move more weight. Very common, and it turns an anti-rotation exercise into a rotation exercise with a heavy load. Film one set from the front; the shoulders should stay level.
Standing too upright. A near-vertical torso shortens the range badly and turns the movement into a shrug. Hinge until you feel the hamstrings load.
Yanking off the floor. Bouncing the plate on the ground between reps kills the tension the exercise depends on. Stop just short of the floor and reset.
Too much weight, too soon. The leverage is not the same as a dumbbell row, and the first session is not the time to find out where the ceiling is.
Two sessions a week is plenty. Pair it with a vertical pull such as pull-ups or a lat pulldown so your back gets both directions, and see the back exercises guide for how the whole thing fits together. More home training ideas in the workouts section.
The lats, mid traps, rhomboids and rear delts do the pulling, with the biceps and forearms assisting. Because you stand in a staggered or hinged position and pull on one side at a time, the obliques and the deep trunk muscles work hard to stop your torso rotating, which is why people feel it in their sides the day after.
No. Wedging the barbell into a corner works, provided you protect the wall with a towel or an old plate. A proper landmine sleeve is smoother, quieter and stops the bar wandering, and most power racks now take one for around £30, so it is a cheap upgrade rather than a necessity.
For most people training at home, yes. The arc of the bar means the load stays closer to your body and the position is easier to hold with a neutral spine, so you get comparable back work with less lumbar load. A barbell bent-over row still builds more raw total-body strength if your back handles it well.
A Meadows row is a specific landmine row variation, named after the late John Meadows, performed side-on to the bar with a staggered stance and a pronated grip on the sleeve end. All Meadows rows are landmine rows; not all landmine rows are Meadows rows.
Start lighter than you expect, because the leverage is different from a dumbbell row. One 20kg plate on the bar is a reasonable first attempt for most people who already train. Add weight only while you can still finish each rep with your shoulder blade pulling back rather than your elbow flaring up.
Easily. You need a barbell, some plates and either a corner or a landmine attachment. It is one of the best back exercises available to anyone without a cable machine or a lat pulldown, which describes most home gyms.
