Sometimes you have the time and inclination to hit the gym for a long leg workout that uses multiple machines and types of free weight. And sometimes you just have 10 minutes, a set of dumbbells, and enough room to stand.
If you have a set of the best adjustable dumbbells you can change the weight as required to suit each exercise, but since you’ll be doing lower body moves that work the biggest muscle groups in the body, a fairly heavy weight is best to provide enough of a challenge to stimulate growth and strength gains.
