When the day that you’re scheduled to go to the gym drops, there’s that little voice in your head that gets creative when it comes to skipping a workout. It’s either too cold or too tired that you promise to go tomorrow, until it never comes. These are 9 of the most common excuses that are scientifically baseless.
9. I’m Still Sore From Last Workout
That post-workout soreness is known as Delayed Onset Muscle Soreness (DOMS). The common assumption we make is that we need to rest the sore muscles to recover, but that’s false. A 2003 study revealed that the most effective way to alleviate the pain of DOMS is to get active. It could be a gentle movement like walking, swimming, or maybe light cycling around the street. This increases your blood flow to the affected muscles to remove the metabolic byproducts and give the nutrients they need to heal.
8. The Weather is Terrible
It’s easy to reason out the rainy day or the chill for skipping an outdoor run or gym. But a 2018 study from Harvard Medical School found that exercising in the cold converts your stubborn white fat (belly and thigh) into active and calorie-burning brown fat. Your body also works harder to maintain its temperature, which means you burn calories by staying warm.
7. Injuries Are Everywhere
While being injured is a valid concern, a sedentary lifestyle is far more dangerous than the active one you’re fearing. The World Health Organization’s 2024 report showed that insufficiently active people increase their risk of death by 20% to 30%. Remember, inactivity drives chronic diseases like heart disease, type 2 diabetes, and certain cancers. Just choose activities you feel comfortable with while increasing their intensity. Learning the proper forms of exercises can build a strong foundation to prepare your body.
6. The Gym is Too Expensive
There’s no doubt that a pricey gym membership eats a lot out of your wallet. But if your finances aren’t committed yet to that gym membership, the most effective workouts are actually free. A study from the International Journal of Environmental Research and Public Health confirmed that simple bodyweight training requires no specialized equipment. You can also practice exercises like squats, push-ups, lunges, and planks even in the comfort of your own home. You can even add in daily walks around the street, and the park is a form of exercise. Also, YouTube is practically free to practice the correct forms of workout.
5. I’m Not Seeing Results
The benefits of exercising actually happen inside your body before they show outside. The timeline actually varies, but the changes are immediate. If you notice, you instantly feel good after one workout, and your sleep quality improves. Within weeks or months, your cardiovascular and energy levels will improve. The immediate things you look for, like muscles and fat loss, happen in six to twelve weeks, depending on consistency. Feeling more energetic and sleeping better is a clear sign that you’re getting the benefits of that workout.
4. The Gym is Intimidating
That’s gymtimidation speaking to you, but here’s a secret: nobody is really paying attention to you as much as you think. Most people are focused on their own workout and goals rather than observing others. Usually, they put in their earbuds to focus. Also, the rise of online fitness classes and community sports leagues makes it easier for you to find a supportive and comfortable environment. The goal is to find a fitness activity you enjoy in a place where you feel confident.
3. I’m Too Old to Start
No one’s missing the window to get active. Around 85 studies published by the BMJ in 2025 showed a powerful message that it’s never too late to start exercising. Research shows that lifelong exercise has a lower mortality risk and that individuals who went from being inactive to active later in life still saw a 20-25% reduction in the risk of dying. You don’t really need to train like you’re in the Olympics, just choose activities that involve you getting your body active.
2. I Don’t Have Time
Even if you have the busiest career, short and intense activities throughout your day are already considered exercise. One study from the University of Portsmouth revealed that short workouts for 10-15 minutes can already provide health benefits. The secret lies in the intensity of workouts like the High-Intensity Interval Training (HIIT). It involves short periods of all-out efforts with a brief rest that improves cardiovascular fitness and metabolic health than traditional workouts. Maybe a quick bodyweight circuit before a shower or a few sets of stairs in the afternoon is enough.
1. I’m Too Tired
Understandably, the last thing on your mind after a long day at work is exercise. However, it’s what your body needs, which is called the energy paradox. According to a Harvard Medical School article, physical exertion actually signals your body to produce more mitochondria in your muscle cells. These are the small power plants that create energy from the food you eat and the oxygen you breathe. Just start slow.
