A 30-Minute Advanced Core and Legs Workout to Spice Up Your Regular Sweat Sessions
Building a strong core and lower body is essential for overall fitness, stability, and performance. Your core acts as the foundation for nearly every movement, helping to protect your spine, improve posture, and enhance balance, according to Harvard Health.
Meanwhile, strengthening your lower body—quads, hamstrings, glutes, and calves—boosts mobility, power, and endurance. Together, they improve athletic performance, support daily activities like walking or lifting, and reduce the risk of injury.
That’s why Or Artzi, CPT, a lead group fitness instructor at Equinox and creator of the fitness platform Orriors, created this advanced core and legs workout to focus your midsection and every muscle group in your legs—and kick things up a notch from your regular strength sessions.
