How to get fit fast with CAR.O.L!

What is fitness?

Cardiorespiratory fitness (or simply fitness), typically determined by measuring maximal oxygen uptake, or VO2max, refers to the highest rate at which oxygen can be taken up and consumed by the body during intense exercise. Historically, the magnitude of an individual’s VO2max has been viewed as one of the most important predictors of endurance exercise performance.


Why is fitness important for health?

Research has recently shown that low levels of fitness better predicts an individual’s risk of developing heart disease and heart-disease mortality compared to traditional cardiovascular (CVD) risk factors. So just how important is fitness to overall health? Consider this, another recent study showed that if we could eradicate low fitness across the population than more premature deaths would be avoided, including those from CVD, when compared to deaths that could be prevented by eliminating traditional risk factors, such as obesity, smoking, hypertension, high cholesterol, and diabetes .

Get fit fast with CAR.O.L!

Clearly, sufficient levels of fitness are paramount to overall heart health. Fortunately, CAR.O.L provides users with potent and time-efficient workouts for improving fitness. 


Our laboratory recently compared fitness gains following both CAR.O.L intense and fat burn rides to traditional workouts adhering to the public health physical activity recommendation of 30min of moderate-intensity treadmill exercise. We had a cohort of 28 men and women train 8wk following either CAR.O.L workouts 3-4 days/wk or moderate-intensity treadmill exercise for 30min on 5 days/wk. Fitness was measured via the gold-standard method of gas exchange collection and analyses. More details on the study design can be found here.


The main fitness findings are illustrated in the adjacent figure. Here are two key takeaways:

  1. CARO.L workouts are by far more time efficient. Total weekly exercise time of traditional workouts was 150min. In comparison, CAR.O.L workouts only took 40min – that’s just 25% the time commitment.
  2. Most impressively, the CAR.O.L group saw a nearly twofold greater improvement in fitness (12.3%) relative to the traditional, moderate-intensity group (6.9%)
