Dumbbell Scissor Kicks (for core)
If you were worried a floor workout would be too easy, this move will set you straight—and fast. This move starts in a hollow hold position: “Imagine doing a crunch but staying at the top,’ Scharff says. From your back, press a set of dumbbells into the air over your mid-chest. Peel your shoulders off the mat while keeping your lower back glued to the ground. Think about pressing the weights toward the ceiling as you scissor your legs, never letting them touch the ground.
This doesn’t have to be a fast movement, just big, controlled kicks. You can also do this move with one heavier weight as opposed to two dumbbells. Either way, go for 50 reps or 45 seconds!
