This 20-Minute Core Workout Is So Good It's Olympian-Approved

In this workout presented by Samsung Health, Olympian and Slay Athletic founder Louise Hazel shares the ab routine that keeps her core stable and strong for runs. Hazel begins with a dynamic warmup that includes rotational exercises to activate your muscles. Then she moves into a circuit that includes beast plank, bird dogs, and heel taps. Hazel also introduces viewers to a vaulter's ab exercise and weaves in plenty of planks throughout the workout. In other words: be sure to take breaks or shake out your wrists as needed. That said, this cross-training routine is perfect whether you're training for short distances or a marathon.

Great runs start with great sleep. With Galaxy Watch7 and the Samsung Health app, track your rest and get personalized tips for how to improve it. Then wake up to your Galaxy AI-generated Energy Score, a comprehensive score based on yesterday's stats that helps you know how to take on today — whether it's time to tackle a long run or take a rest day.
