Pre-workout supplements are designed to boost energy, increase focus, and enhance endurance while engaging in physical exercise. But what if you take these supplements without hitting the gym? In this article, we will delve into the world of pre-workout supplements to see how they function and whether they can be used without following up with a workout.

What is Pre-Workout?

Pre-workout is a term used for supplements taken prior to physical exercise. These products are formulated with various ingredients designed to help individuals perform at their best during workouts. Common components include amino acids, caffeine, vitamins, and minerals.

Can you take pre-workout without working out?

Taking pre-workout supplements without working out presents a unique consideration. These supplements are specifically formulated to enhance energy, focus, and endurance for physical activities. Without the corresponding exercise, some of the intended benefits may not be realized, and the impact on the body can differ.

For instance, ingredients like caffeine may still provide a temporary boost in energy and alertness, while others like creatine could have cognitive benefits. However, consistent use of pre-workout supplements without physical exercise might lead to unintended side effects or imbalances, as they are designed to complement an active lifestyle.

The effects of pre-workout supplements during rest depend heavily on the type of pre-workout supplement you are taking. Today, we’ll look at two of the most popular pre-workout supplements: nitric oxide boosters and creatine monohydrate – and explore their effects on the body with and without working out.

Nitric Oxide Boosters

Nitric oxide is a naturally occurring molecule in the body that plays a vital role in vascular regulation, helping to dilate blood vessels for better blood flow. Nitric oxide boosters, commonly found in pre-workout supplements, aim to increase the levels of this molecule. The intended result is enhanced delivery of oxygen and nutrients to muscles during exercise, potentially improving workout performance and recovery.

On Workout Days: For those engaging in exercise, nitric oxide boosters can amplify performance by enhancing blood flow to muscles. This improves oxygen and nutrient delivery, contributing to better strength, endurance, and recovery (1).

On Non-Workout Days (for those who exercise regularly): Even on rest days, nitric oxide boosters might help recovery from previous workouts by maintaining increased blood flow.

For Individuals Who Don’t Work Out at All: If you’re not engaging in physical exercise at all, the benefits of nitric oxide boosters may be limited. Though there might be feelings of increased energy, without the physical demand, the full potential of these supplements might not be realized, and there could be side effects such as blood pressure changes.

Creatine Monohydrate

Creatine monohydrate is a popular supplement known for its performance-enhancing effects in high-intensity workouts. It’s a compound that’s naturally found in muscle cells and helps produce energy during heavy lifting or high-intensity exercise. Supplementing with creatine monohydrate can increase the body’s stored creatine, thus helping to improve strength, increase lean muscle mass, and potentially provide cognitive benefits.

Creatine monohydrate is not only recognized for its ability to enhance athletic performance but also for its potential cognitive benefits. Here’s a closer look at its effects across different scenarios:

On Workout Days: For athletes and fitness enthusiasts, creatine monohydrate can boost power and strength during high-intensity activities like weight lifting or sprinting (2). It’s most effective when taken as part of a pre-workout routine.

On Non-Workout Days (for those who exercise regularly): Creatine may still assist in recovery by replenishing energy stores in muscles. Moreover, consistent supplementation could potentially aid cognitive function by enhancing the brain’s energy metabolism, even on days without physical activity.

For Individuals Who Don’t Work Out at All: The role of creatine in those not engaging in physical exercise extends beyond muscles. Some studies suggest that creatine supplementation might improve mental clarity, memory, and overall cognitive function (3). This can be especially relevant for vegetarians or those on a low-meat diet, as creatine is mainly found in meat and fish. However, more research is needed to establish these effects firmly, and long-term use without exercise might still lead to health implications such as weight gain from increased water retention.


In conclusion, nitric oxide boosters and creatine monohydrate are pre-workout supplements designed for enhancing physical performance and may also offer cognitive benefits. While they can have some effects outside of exercise, their primary functions are most realized in conjunction with physical exertion. Utilizing these supplements requires an understanding of their complex nature and, ideally, guidance from healthcare providers, whether used in or outside of traditional workout routines.
