Even a single set of 12 reps with a heavy enough weight can help build your muscles versus 3 sets at a lighter weight.

When you achieve the right weight for your fitness goals, an unmistakable feeling comes with it—a sense of accomplishment.

Why are rubber weights so expensive? ›

If it's one solid piece it's just 20 pounds total, like the hand dumbbells. The ones you lift over you head, have plates you put on each end and those would be 20lb each. If it's one solid piece it's just 20 pounds total, like the hand dumbbells.

(Note: when we talk about weight, it is ALWAYS the weight of all plates (on both sides) plus the barbell.

If it's single arm curls or another iso exercise I log the dumbell weight, if it's a compound lift like dumbell bench or dumbell deadlift I log the total combined weight.
