I recently discovered a Pilates-meets-strength training routine while trying to fit a 15-minute core workout into a busy schedule. Described as an “express core workout”, it’s designed for days when time is tight but you still want a session that feels effective and purposeful.
According to Izzy, the instructor behind the Pilates By Izzy YouTube channel, this routine blends strength training principles with Pilates-style movement to form a continuous flow that challenges strength, endurance, and coordination in a short amount of time.
How the Express Core Routine Is Built
The workout focuses on long, fluid sequences that gradually build intensity. These movements are designed to improve both muscular endurance and core strength through controlled, intentional motion.
Because the exercises are layered and require steady control, the routine is best suited for those at an intermediate fitness level. The pace encourages precision rather than speed, making proper execution an essential part of the workout.
Key Safety Guidelines to Keep in Mind
Izzy advises participants to take breaks when needed and modify exercises based on their individual abilities. She also recommends speaking with a healthcare professional before beginning any new fitness routine.
She emphasizes the importance of never pushing through pain, especially if discomfort arises in the neck or lower back. This workout is not recommended for those who are pregnant, have a heart condition, or are managing an existing injury or health issue. Above all, maintaining proper form and listening to your body should take priority over intensity.
Equipment Needed and Muscles Worked
In addition to a mat, the only equipment required is a Pilates ball. The routine targets the entire core, engaging not just the abdominal muscles but also the upper and lower abs and the obliques.
Although this session appears as the second day of a 25-day challenge, it works perfectly as a standalone workout. The sessions are free to access, and there’s no need to complete previous workouts to benefit from this one.

Warm-Up and Flow of Movements
The warm-up is brief yet effective, moving through a yoga-inspired sequence that includes child’s pose, downward dog, and cat-cow. A gentle backbend similar to upward dog is also included, with options to bend the elbows or rest on the forearms for added comfort.
Once the main workout begins, the Pilates ball is used to guide each movement. Izzy’s cues are clear and well-timed, with a strong focus on breath control. She consistently signals when to inhale and exhale, helping activate the core muscles and engage the diaphragm effectively.
Why This 15-Minute Workout Feels So Challenging
The slow, controlled tempo keeps constant tension on the muscles, leaving little opportunity to rush through the exercises. Over time, this method helps develop a stronger mind-muscle connection, improving both control and body awareness.
While the routine includes only a limited number of exercises, you spend more time on each as movements are gradually layered. This Pilates-style structure increases time under tension, allowing muscles to work harder in less time.
The higher repetition ranges test muscular endurance and reinforce consistent breathing. You will feel the burn, but with just 15 minutes on the clock, the workout moves quickly. For best results, it’s important to properly engage the core and warm up the hip flexors, as the routine also incorporates leg-focused movements.
