As the weather warms up, there’s something motivating about getting outside, moving your body, and building the kind of fitness that helps you feel strong and energized all summer long. This workout combines running with a challenging core circuit to help improve both core strength and VO2 max—your body’s ability to use oxygen efficiently during exercise.

The one-mile run will elevate your heart rate and challenge your endurance, while the core work targets stability, strength, and control through multiple planes of movement. It’s a simple but effective workout that will leave you sweaty, stronger, and feeling accomplished without needing a ton of equipment or time. Find all of our minimal equipment workouts here.

Workout Description

At the start of the workout, complete a 1 mile run. The goal is to move with strong, steady effort throughout the mile — maybe not your fastest mile ever, but a pace that feels challenging and intentional. Once you return from the run, you’ll move directly into the core circuit.

Complete 10 weighted sit-ups, 20 Russian twists, a 45 second plank, and 12 alternating V-ups. Repeat the full core sequence for a total of 4 rounds. Focus on controlled movement, core engagement, and maintaining good form as fatigue sets in.

Equipment Needed

• Dumbbells

Modification Options

Beginner: Run/walk the 1 mile at a pace that allows you to keep moving consistently. For the core work, complete all movements without weight and reduce reps as needed to maintain good form. You can also shorten the plank hold to 20–30 seconds if necessary.

Advanced: Push the pace on the 1 mile run and challenge yourself to maintain strong effort throughout. Increase the weight for the weighted sit-ups and Russian twists, and swap the alternating V-ups for traditional V-ups to make the movement more challenging. You can also add a fifth round of the core circuit for an extra endurance challenge.
