Two dumbbells, 30 minutes and this full-body workout to burn calories and build muscle

If you’re in two minds about working out because you feel that you’re short on time, then this high intensity resistance training (HIRT) workout is for you. Not only will it stimulate all the muscles in your body, including your upper body, lower body and core, but it’ll only take you 30 minutes to complete. All you need is a pair of dumbbells, two large water bottles or even a pair of kettlebells will do – you choose!

While HIIT usually focuses on bodyweight exercises and cardio movements, HIRT incorporates free weights, like dumbbells or resistance bands. "HIRT maximizes energy expenditure, resulting in optimal calorie burn and cardiovascular output during your training sessions," says TRX Training. It's also a lot lower impact than HIIT too, as it doesn't involve high-impact cardio exercises, like burpees. It's therefore a good alternative if you suffer from joint pains, as you still get the cardiovascular benefits and weight training, without the high impact.

For this workout you've got seven exercises to get through and you'll do each one for 45 seconds of work, with a 15 seconds rest. Once you've completed one entire round, rest for 60 seconds, before repeating it two more times. Make sure you're wearing your best workout shoes too, to provide extra stability during each exercises. Here's your workout:

• Curtsy squat with a bicep curl
• Lunge with overhead Press
• Squat with an overhead Press
• Push-ups
• Comandos
• Sit-ups
• Wall sit
