This Challenging 10-Minute Lower Abs Workout with Weights Will Leave You Sore

This lower abs workout with weights will tone and tighten your core in just 10 minutes. No dumbbell? Don't worry! Every move in this workout can be done with or without a weight. But keep in mind that by adding a single dumbbell (or a small medicine ball or kettlebell), you'll fatigue your muscles much faster and really set your abs on fire. (Translation: It'll really hurt to laugh tomorrow.) Blast through these moves for an intense abs-focused workout, or tack on a lower body booty workout and upper body arm workout for a full body burn.

How it works: Do each of the moves in the video. If you want more of a sweat, repeat this circuit one or two more times for a 20- to 30-minute lower abs workout.
