barbell

An unweighted squat will still engage all those muscles if it’s done properly, but a sloppy squat under a loaded barbell could leave some of them out—which is inefficient at best, and potentially dangerous at worst.

A trap bar deadlift is the same motion, except instead of grabbing a barbell you use a contraption that you stand inside.

Another is a traditional back squat, where you hold a barbell up by your shoulders.

If you’re planning to wear it while clanging barbells or venturing out into rough terrain for trail runs, however, the jump to the Apple Watch Series 6’s stainless steel case with the sapphire crystal cover is a smart move.
