HASFit Review

100 million free workouts at your fingertips — it sounds impressive, but are these fitness videos actually effective? Is the program legitimate? We put on our workout gear to find out.

We tried the workouts on YouTube, read through hundreds of user reviews, downloaded the HASFit app, and reviewed dozens of medical journals on the benefits of exercise. Here’s our bottom line on this online exercise platform.

What Is HASFit?

HASFit, short for Heart and Soul Fitness, is an online fitness program built around free, full-length workout videos for every fitness level, with a library exceeding 100 million free workouts across YouTube and HASFit.com. The channel has been named a Top 10 YouTube fitness channel for four consecutive years, and an app is also available for Android.

Beyond workout videos, the platform offers meal plans and fitness tips aimed at improving overall health and well-being, while maintaining a deliberately neutral stance on religion or belief systems.

Workout categories span a wide range, including Abs, HASFit for Seniors, Beginner, Cardio, and Warm-Up, letting users pick routines that match their goals. Most workouts require no equipment, though a handful call for dumbbells. HASFit also sells a small merchandise line, including performance t-shirts, tanks, sweatshirts, hoodies, hats, and e-books.

Does the Research Support It?

• Journal of Physical Therapy — Shows regular exercise improves both resting metabolic rate and anaerobic threshold.
• Sports Medicine — Suggests activity decreases fatigue and increases energy levels.
• Frontiers in Psychiatry — Found regular exercise positively impacts mental health.

Is There a HASFit App?

Yes, a free app is available on Google Play and the Apple App Store, letting users build a customized fitness plan and stream (or download) workouts for offline use.

Is HASFit Available Live?

No, HASFit doesn’t currently offer live-streamed workouts.

Who Created HASFit?

Founded in 2012 by Josh and Claudia Kozak, HASFit was built on the idea that exercise should be freely accessible, since it supports well-being across mind, body, and soul, according to the founders. Josh, a certified personal trainer with a strong presence in health and wellness social media, has developed more than 25 fitness apps, including Gymatic — reportedly the first app capable of tracking and counting exercise reps.

Claudia Kozak, co-founder and a personal trainer and fitness coach in her own right, brings an upbeat, motivational presence to many of HASFit’s YouTube workout videos. Both Josh and Claudia appear in the workouts themselves, giving the platform a consistent, hands-on feel.

How Does HASFit Work?

Users can stream workouts through the app, website, or YouTube, with sessions ranging from 5 to 60 minutes. Whether it’s a good fit really comes down to whether working out at home suits your lifestyle.

What’s Included in the HASFit Program

HASFit offers both standalone videos and full 90-day workout programs, spanning categories like Warm-Up, Fat Burning, Beginner, Yoga, HIIT & Tabata, MMA, Muscle Building, Strength Training, Cardio, Kettlebell, Seniors Low Impact Total Body Cardio, Abs, Kickboxing, and Flexibility Training.

In each video, Josh demonstrates the advanced version of an exercise while Claudia performs a simplified variation for beginners — a format designed to build strength, burn fat, and improve cardiovascular health for users at any level, at home, on their own schedule. The app also enables offline workouts when internet access isn’t available.

Here’s what the research says about a few of HASFit’s core workout categories and weight loss:

HIIT: A 2019 study in Applied Physiology, Nutrition, and Metabolism found high-intensity interval training more effective for weight loss than moderate-intensity continuous training.

Yoga: According to Evidence-Based Complementary and Alternative Medicine, “Yoga interventions improve obesity-related outcomes including body mass index (BMI), body weight, body fat, and waist circumference.”

Cardio: Progress in Cardiovascular Diseases notes that physical activity and exercise training are “associated with reduced CV risk, improved cardiometabolic risk factors, and facilitated weight loss through creating a negative energy balance.”

Strength Training: Genuinely useful for weight loss and essential for bone health, though cardio tends to edge it out for pure calorie burn, according to Sports Medicine.

Kickboxing: True kickboxing takes years to master, but noncontact circuit-training variations have been developed to bring similar intensity to a broader audience, according to the Journal of Strength and Conditioning Research.

Does It Integrate With Wearables or Health Apps?

You can wear your favorite fitness tracker during a workout, but the app itself doesn’t sync or store data from external devices.

HASFit and Weight Loss

HASFit includes several workouts specifically geared toward weight loss. Exercise supports weight loss primarily by helping create a calorie deficit — burning through calories faster than diet changes alone typically allow.

A 2013 study in Progress in Cardiovascular Disease confirms increased physical activity as an effective tool for weight control, and research in The Annals of Medicine similarly points to exercise as critical for maintaining a healthy weight long-term.

HASFit’s Facebook page features plenty of positive testimonials from community members crediting the workouts with real progress on their weight-loss journeys.

HASFit Warnings and Side Effects

As always, check with a physician before starting any new exercise routine. Beyond that standard precaution, there don’t appear to be any specific warnings tied to HASFit’s workouts.

Pros and Cons

Pros:

• Completely free
• Thousands of positive reviews
• Dedicated senior-friendly workouts
• Convenient YouTube access
• Massive workout library for every fitness level

Cons:

• No live-streaming option
• Some users report technical issues with the app

Bottom Line on HASFit

HASFit offers a genuinely impressive variety of free streaming workouts, and it’s clear Josh and Claudia Kozak are passionate about helping people build healthier lives. That said, the platform has real limitations — without reliable internet, streaming workouts simply isn’t an option, and the program on its own doesn’t offer a complete health package.

Exercise alone rarely produces lasting weight loss without equally smart dietary choices alongside it. A well-rounded fitness routine like HASFit pairs naturally with mindful eating habits and consistent daily choices — the combination tends to matter far more than any single workout program on its own.
