<p><strong>LES MILLS GRIT</strong> is a 30-minute high-intensity interval training (HIIT) workout, designed to improve strength, cardiovascular fitness and build lean muscle. This workout uses barbell, weight plate and bodyweight exercises to blast all major muscle groups. </p>
<p>High-intensity interval training (HIIT) is any workout that involves short, intense bursts of effort followed by periods of recovery. The idea is that you go as hard as you possibly can for a short time, rest and then do it again. The intense intervals, particularly the use of the recoveries, allow you to keep reaching your maximum training zone, which is where the results kick in.</p>
<p>In a 30-minute LES MILLS GRIT workout you can expect to burn around 400 calories* – and that’s just the beginning. LES MILLS GRIT puts your metabolism into overdrive and generates accelerated changes in body composition.</p>
