Sculpt your core in just 15 minutes with this standing abs workout

Sit-ups aren't the only move you can use for a scorching ab workout. If they hurt your back, or you just find them a bit boring, there are plenty of other effective options out there for a comprehensive core workout. 

For example, you can try using one of the best ab rollers to build muscle in your midsection. Alternatively, this equipment-free session from workout instructor Maddie Lymburner (better known as MadFit) allows you to strengthen your abs and boost your cardio, all from a more spine-friendly standing position.   

In a video on her YouTube channel, Lymburner first leads viewers through a quick warm-up consisting of step-jacks and cross-punches. Then she dives into the main workout itself. 

In this, each exercise is paired with another one to form a "superset". This means they are performed back-to-back with no rest in-between, helping raise your heart rate and boost your metabolism. 

You are challenged to complete thirty seconds of both exercises, resulting in one minute of work in total, followed by 15 seconds of rest to catch your breath.  Repeat each superset twice before moving on to the next one. 

If this sounds confusing, never fear. Just follow Lymburner's lead in the follow-along video below, making sure to listen to her form cues to ensure good technique.

This workout takes just 15 minutes and (like other HIIT workouts for fat loss) combines a circuit of exercises with low rest times to create a session that gets you breathing hard, boosting your cardiovascular fitness and burning plenty of calories. 

However, it differs from similar sessions in that it's designed with beginners in mind, using only low-impact movements and no equipment. This decreases the chance of injury and means it can be performed at home or at the gym.

However, if muscle gain is your goal, performing the right exercises is only part of the battle. You will also have to eat enough protein to support your training, as this macronutrient is essential when building muscle. 

This should mostly be done through eating high-protein foods (find out about the different types of protein here) but if you struggle to hit your daily quota you can up your intake with the best protein powders for weight loss.
