How Does C25K Claim to Work?

Details on the C25K Program
C25K is a progressive app that spans eight weeks. The premise of the program is that users start out alternating between walking and running, with walking being the focus in the beginning.
As the user gets stronger, the balance between walking and running eventually favors running, which is how the user trains for a 5K race.
There are three workouts each week with break days between the workouts. You can expect to workout between 30 and 40 minutes, including five minutes to warm up and five minutes to cool down. So, you’re actively working out for 20 to 30 minutes.
Does it Integrate With Wearables or Health Programs?
Yes, C25K integrates with a variety of wearables and programs. You can integrate with:
C25K and Weight Loss
If you go based off of the name of the program, Couch to 5K, you can assume weight loss is possible. The design was developed to help people new to running, or people stuck on the couch, gradually improve physical fitness. Anyone who moves from not exercising to training for a 5K will likely lose weight, but only if a well-thought-out eating plan is followed. You can’t eat 5000 calories a day and expect to lose weight no matter the program you follow.
Research published in a 2016 edition of the Journal of Sports Medicine and Physical Fitness shared, “An average running distance of more than 5 km per week in runners who took up running to lose weight combined with a targeted diet change seems effective in reducing fat mass over a one-year period among novice runners.”
It’s also important to note that physical activity is about more than just losing weight. Activity can offer improvements in overall health, and some condition-specific improvements in obesity-related conditions, in the absence of weight loss, as per Progress in Cardiovascular Diseases.
C25K Warnings and Side Effects
Yes, C25K is designed for beginners, but that’s not to say everyone should jump right in. If you have concerns about your health, have been diagnosed with a medical condition of any kind, are taking medication, are pregnant, or a long list of other health considerations, talk with your healthcare provider before you start to train for a 5K.
Some activity-specific side effects may include:

Bottom Line on C25K
We love C25K. The app has been around for years, and Zen Labs has done nothing but improve the program over time. It starts slow, progresses over eight weeks, and works for new runners, as well as current runners. The biggest downside is that the program may not be suitable for some, based on weight, activity level, and overall health.
Weight loss is a complicated process, but there is help out there to make everything run more smoothly.
Among the best in apps for weight loss is Noom. The program incorporates psychology, health education and lessons, changes in eating habits, and personal coaching to ensure the user loses weight and keeps it off. Noom has been clinically proven to promote weight loss and weight maintenance.
