Going to Orangetheory Fitness is a proven way to improve your health and shred extra pounds from your love handles. However, what happens if you’re a busy guy or gal and you have just one day per week to train? Today I will explain if going to orange theory once a week is enough, based on your fitness goals.

In general, doing orange theory fitness once a week is better than nothing. People who don’t have time for more frequent exercise still get the health benefits of doing just one high-intensity workout every seven days. However, it can take 6-12 months to see significant results.

I will also show you some interesting studies that explain the advantages of doing high-intensity interval training like orange theory fitness, even if it’s only one day a week.

Is Orange Theory Once A Week Worth It?

Stating a fitness regime to get into tip-top shape takes a lot of time and dedication. This can be difficult, especially if you’re wearing many hats during the day.

Many of us juggle one or more jobs, have family responsibilities, and have early-morning or late-night clients. Needless to say, it’s hard to combine that with consistent exercise.

One of the ways you can get into shape is by doing orange theory fitness, which is a combination of strength and cardiorespiratory fitness. Each workout delivers a mix of running/walking, rowing, and functional resistance training using TRX and weights.

However, what happens if you only have one day per week?

Overall, doing orange theory once a week is worth it because you can still improve your health, body composition, and performance. Studies have shown that doing resistance training once or twice per week delivers muscle strength gains similar to 3 days per week training.

What Happens If You Only Do OTF Once A Week?

One of my clients is a busy software developer who spends most of her days behind the desk. When she sign up for my training, she told me she only have one day per week to train.

Six months later, Frances was in the best shape of her life.

In other words, going to orange theory fitness one day per week it is worth it but you need to accept it will be a long road. You also need to have realistic expectations about the results you want.

This happens regardless if you’re doing orange theory once a week or four times a week (as they recommend).

Dr. Willemijn AM. van Gemert from the University Medical Centre in Utrecht documented the effects of weight loss after doing diet alone versus exercise alone.

  • The exercise group was training for 4 hours per week using a combination of resistance training and endurance.
  • The diet group did not exercise, instead, they have prescribed a caloric restriction diet of around 3500 kcal per week (which equals to 500 calorie deficit per day).

See the graph below.

As you can see, 16 weeks of creating a 500 kcal energy deficit per day lead to similar changes in body weight and body composition (van Gemert et al. 2015).

NOTE: You can learn more about how effective is to do a “500 calorie deficit” per day in my article here.

Of course, the study also highlights the additional benefits of doing strength training more frequently like preservation of lean mass, better physical fitness, and improved hormonal profile.

“All healthy adults aged 18–65 yr should participate in moderate-intensity aerobic physical activity for a minimum of 30 min on five days per week, or vigorous-intensity aerobic activity for a minimum of 20 min on three days per week.” (ACSM).

  • Ride a bicycle instead of driving the car, especially during the nice summer weather.
