SIT, or sprint interval training, is a highly effective workout that consists of max effort sprints with extended periods of rest in between. It involves short intervals consisting of all-out, 100% max efforts, followed by longer rest periods. Because the intensity is so high, the rest periods are longer and the duration of the workout is shorter. A SIT workout may look like 4-8 all-out sprints for 5-30 seconds followed by a full recovery, say 2-4 minutes depending on individual fitness level. This recovery could look like complete rest where you sit or stand in place or it could look like a light jog/walk. SIT is a quick and convenient full-body workout that targets all major muscle groups while also raising your heart rate for a well-rounded workout. The 7-minute workout, which is a high-intensity workout that alternates between 30 seconds of high-intensity exercise and 10 seconds of rest, includes exercises such as wall sits, pushups, and crunches. However, it is not specifically a "sit workout" as it includes a variety of exercises.
