Kettlebell swings are easy? Easy to f up!!

How you pick the kettlebell up matters just as much as anything else, especially when using a HEAVY KB.

Wrong: standing directly over, deadlifting up, starting first swing totally on your own.

Right: stand ~6” away from the KB, let the weight swing itself for the first one.

Epically easier.
