This doesn’t mean all kettlebell squats and chest presses but strength is key to balance out all of the other disciplines. Your body weighs a lot and gravity is smart and quite often that is enough, especially if you are hanging from a bar or a TRX. If you’re sat at a desk all day you need to strengthen your hip flexors as they’ll often end up weak. If you want to learn how to handstand you need to strengthen your scapula. I’m also a big believer in core strength being literally the centre of your physical universe- it will be your friend in all other areas of your training and in everyday life. You might also get yourself a banging set of abs.
