Public health guidelines suggest 30-60 minutes of moderate-intensity exercise on most days of the week. However, despite overwhelming scientific evidence that regular activity is effective in the prevention of chronic diseases and premature death, most adults fail to meet even the minimum physical activity requirement.
Countless studies have shown that the most commonly cited reason for not exercising is a “lack of time” (Godin et al., 1994). This finding is universal; regardless of age, ethnicity, sex, or health status, people report lack of time is the primary reason for their failure to exercise on a regular basis.
Given that lack of time is such a common barrier to exercise participation is why I developed our Xpress Workouts program.
I recently read a study on the Gatorade Sports Science Institute (GSSI) website by Martin J. Gibala, PhD. on “High Intensity Interval Training (
“...From a practical perspective, one of the most striking findings from our recent studies was the dramatic improvement in exercise performance during tasks that rely mainly on aerobic energy metabolism, despite the very low training volume (Burgomaster et al., 2005; 2006; 2007; Gibala et al., 2006). In our initial study (Burgomaster et al., 2005) subject doubled the length of time that exercise could be maintained at a fixed submaximal workload - ~26 min to 51 min during cycling at 80% of pre-training VO2peak – after only six

Once again more positive evidence mounts for high intensity short duration exercise such as with our Xpress Workouts program.
