The Turkish get up is one exercise where you start flat on your back with a weight punched towards the ceiling and, without ever letting that weight drop, work your way up to standing and back down again. It looks strange the first time you see it, and it humbles nearly everyone who tries it with real load. But it teaches shoulder stability, core control and full-body coordination better than almost anything else you can do with a single kettlebell. It has roots in old-time strongman training, physios use versions of it for shoulder rehab, and kettlebell coaches treat it as a rite of passage. Here is how to do it, what it works, and how to build it up without hurting yourself.
You need one kettlebell or dumbbell and a clear patch of floor about the length of your body. Start light. If you have never done one, do the whole sequence with an empty hand or a shoe balanced on your fist first, so you learn the shape before you add load.
We will describe it for the weight in your right hand. Swap sides to repeat.
The one cue that keeps you safe
Keep your eyes glued to the bell from the floor until you are standing, then switch to looking straight ahead on the way back down. Watching the weight keeps your shoulder packed and your arm truly vertical, which is exactly where it needs to be to hold load overhead. Lose sight of it and your arm drifts, the shoulder unpacks, and that is when reps go wrong.
The get up is a full-body exercise dressed up as a shoulder move. Because the weight stays overhead through every position, the demand shifts around your body as you change shape.
If you want a bell that suits this movement, a smooth handle and an honest weight marking matter more than fancy coatings. Our pick of the best kettlebells in the UK covers what to look for.
The NHS recommends strengthening work covering all the major muscle groups, including shoulders, back and legs, on at least 2 days a week, and a single get up ticks a surprising number of those boxes at once.
Rushing it. The get up is a slow exercise. Blast through it and you skip the positions that actually build control, and you put your shoulder in a bad spot at speed. Treat each step as its own move, pause, then go to the next.
Losing sight of the bell. The moment your eyes leave the weight on the way up, your arm tends to drift out of vertical and the shoulder unpacks. Watch it until you stand.
A soft, bent wrist. If your wrist folds back, the load hangs off the joint instead of stacking through your forearm. Keep the wrist dead straight and the knuckles pointing at the ceiling, as if you are holding a tray of drinks you refuse to spill.
Collapsing the down leg. During the sweep and the half kneel, people let the back knee crash down or the hips sag. Keep tension in that trailing leg and control the descent, especially on the reverse when you are tired.
Keep it low and clean. This is a skill and a stability exercise, so quality beats volume every time.
Two or three sessions a week is plenty. Because each rep is slow and demanding, you get more from five perfect reps than from twenty sloppy ones. Once your right side feels steadier than your left, spend an extra set on the weaker side to even things out. The kettlebell swing pairs well with the get up on the same day if you want a compact, two-move kettlebell session, and the goblet squat rounds it out with some straightforward leg volume.
Almost all of them, but the standouts are your shoulder and rotator cuff (holding the weight locked out overhead the whole time), your core and obliques (bracing and rotating as you move through each position), and your glutes, hips and quads (driving the bridge and standing up). Your grip and forearm work hard too, because you never put the bell down mid rep. It is one of the few moves that loads your whole body in a single continuous exercise.
Lighter than your ego wants. Learn the pattern with no weight at all, or a shoe balanced on your fist so you get instant feedback if your wrist drops. Once the sequence feels smooth, most people start with an 8kg to 12kg kettlebell and stay there for weeks. The get up rewards control, not load, so nail every position before you add a single kilo.
Yes, as long as you break it into chunks. The full get up has a lot of steps, and trying to learn it in one go with weight overhead is how people wobble and give up. Practise the first half (lying to half kneeling) on its own, then the stand, then link them. Beginners often get more out of it than advanced lifters because it exposes weak links in shoulder stability and hip mobility fast.
A kettlebell is the classic choice and slightly kinder on your wrist, because the load sits in the meat of your palm rather than pressing on the back of your hand. A dumbbell works fine and is easier to find if that is all you own. Hold it vertically, keep your wrist dead straight, and the movement is the same. Start with whichever you have.
Keep the numbers low. One to five reps per side is plenty, because each rep takes 20 to 40 seconds and demands full concentration. A common approach is 3 to 5 singles per side, resetting between each. Two or three sessions a week builds the skill without frying you. This is quality work, not a rep-chasing exercise.
It is one of the best moves for it. You hold the weight locked overhead through every angle, from flat on your back to fully standing, so your rotator cuff and scapular muscles have to keep the joint packed the whole way. A review of kettlebell training singles the get up out for exactly this: building stability and coordination across many muscle groups at once.
