A thought when reviewing my photos on my laptop (vs my phone),

Tapping the left and right arrow button is a more efficient movement than having to ‘swipe’ for next on your phone.

Similarly speaking, kettlebell movement and workout as very efficient because to warmup, all you gotta do is the ‘goblet squat’ hip opener stretch/warmup, then you can just jump into the (two armed) then eventually 1 armed swings.
