Are you ready to build an insanely strong core? (Hint: Whether you're feeling tired, burnt out, or just straight-up lazy, the answer should always be yes.)

Take on six rounds of one-arm dumbbell snatches, one-arm shoulder presses, cross-body mountain climbers, and leg raises to get a kick-start and give your muscles the burn they've been missing. They'll force your body to support the weight unilaterally, meaning you'll have to contend with imbalanced force—and that translates to practical, real-world strength.


Do this workout as a circuit, meaning you'll complete each exercise consecutively without rest. Once you've finished all exercises, rest for 30 to 60 seconds. Repeat the entire circuit for six rounds.

Depending upon your ability, you may shorten or lengthen the rest periods between circuits. You may also complete more or fewer rounds.
