Sit-ups and crunches are staple exercises for a reason; they’re an effective way to build stronger abs. But they can also get boring fast, so it’s important to keep your mid-section routines varied, like with this short, equipment-free core workout.

All you need is a bit of space, and one of the best yoga mats can be handy if you want to make the floor-based moves more comfortable, but it’s not essential. There are some crunches, but you’ll only do these crunch variations for about a third of the routine, leaving plenty of time for other exercises.

The short routine comes from fitness duo Tiff x Dan, and works your abdominal muscles, including the rectus abdominis six-pack abs muscle, and strengthens your core, even when you’re tight on time. Plus, you can repeat the 15-move circuit up to three times for an extended core workout.

However, to get the most from your training, it’s important to get your technique right, as it’s easy to accidentally arch your lower back during abs exercises rather than engage your core. Fortunately, Tiff demonstrates all the exercises, so you can perfect your form before starting.

To pack 15 exercises into a 10-minute session, you’ll do each move for 30 seconds, take a 10-second rest, and then start on the next exercise. If you do repeat the circuit, it’s worth taking an extended break between sets (around 30-40 seconds) to recover before starting again.

This style of exercise is known as high-intensity resistance training (HIRT), where the aim is to train intensely for short periods with minimal rest. It’s similar to high-intensity interval training (HIIT) but with a focus on muscle-building moves instead of cardio-focused exercise.

But both techniques help you fit in an efficient workout even when you’ve got a packed schedule. Plus, since you don’t need any equipment for this particular routine, you can do it whenever you have a spare moment, even while traveling or away from home.

HIRT workouts also help raise your heart rate, so you burn more energy than during a steady-paced equivalent routine. Plus, sustaining this high heart rate helps boost your metabolism, the amount of energy you burn throughout the day, which is important if you’re hoping to burn fat.

Of course, you’re not likely to see tangible metabolism-boosting, fat-burning effects from a single 10-minute session, but if you add Tiff x Dan’s abs workout to your regular routine, or repeat the circuit several times, you’ll notice the effects within a few weeks.

But working your mid-section doesn’t just mean developing visible abs, as you’ll also strengthen your core — a collection of mid-body muscle that connects your upper and lower body, and is responsible for your balance, stability, and posture.

So, taking on an abs workout does build core strength, but if you’re looking for these fitness-boosting effects, you’ll also want to add dedicated core workouts to your routine. Although, if you’re a fan of efficient exercise, it’s also worth considering compound exercises.

These work several muscles simultaneously and often utilize your core for balance, especially if you’re training with weights like adjustable dumbbells or kettlebells. This way, you can build muscle, work your midsection, and raise your heart rate (if you arrange them as a HIRT workout) in a single session.
