I’m going to start doing Turkish get-ups again. I fell out of the habit a couple years ago. Turkish get-ups promote flexibility, balance, joint range of motion, and strength. If you’re just doing the Big Five exercises, TGUs will strengthen some of the smaller muscles (and portions of major muscles) you may be neglecting.
Below are a couple YouTube examples. They are not complete tutorials. You can use a dumbbell or kettlebell. Start with either no weight in your hand, or just a small one. Then work up to higher weights as you get stronger.
These videos may only show how to work one side of the body; you work both sides, of course, and call it a pair. I used to do only five pairs with a 25-lb dumbbell. In weightlifting lingo, you’d call that 1 set of five reps (repetitions). It was exhausting.
Do enough reps and it will be both strength and aerobic training.
