ALL LEVELS / core and oblique workout / 15 minutes

Do you usually leave your abs as a finisher, only to skip them faster than ads on YouTube? You’re not alone. But your core deserves more than a last-minute slot. A strong core and defined obliques do more than make you look good shirtless. They support better posture, improve balance, help prevent injuries, and add power to nearly every movement you make, both in and out of the gym.

Start reaping all those benefits with this core and oblique workout. It consists of 4 exercises performed over 3 rounds, with 30 seconds of rest between exercises and 1 minute between rounds. In total, this workout will take you 15 minutes to complete.

  1. Hanging leg raises – 12 reps
