Are you wondering how much you should rest after each exercise? How many reps you should do to burn fat as quickly as possible? Well here are some tips: For each exercise, you’ll work as hard as you can for 30 seconds. That means you try to get as many reps as possible every single time. After a round or two, 30 seconds starts to feel like 30 minutes! After each exercise, you’ll only rest 15 seconds, which is just enough time to get a sip of water and catch your breath before you get right back to work. These short intervals of work and rest mean the workout will only take you about 15 minutes to complete. You can get in, get the job done, and get out! The best thing about this workout is that it’s great for anybody. The bodybuilding enthusiast, recreational athlete, or gym newbie can all benefit from this fat-burning workout. It will burn calories and improve your overall conditioning level. Because this workout is only 15 – 20 minutes, it fits perfectly into your daily exercise regimen. You can do this circuit workout before or after your regular weights workout, you can split it and do half before and half after, or you can expand it and get an even more intense single cardiovascular session.
