Morning vs. Evening Workouts: Which Is More Effective?

Incorporating exercise into your daily routine can effectively enhance your mood, alleviate anxiety, and promote overall mental well-being. However, the time of day you choose to work out can influence how these benefits manifest. Understanding the nuances of morning versus evening workouts can help you optimize your fitness journey.

“Morning workouts are often associated with increased alertness and better emotional regulation throughout the day,” explains fitness expert Coxall. “Conversely, evening sessions can serve as a significant stress outlet after a long day, enabling individuals to mentally unwind.”

Surprisingly, the reverse dynamic also holds true. A meta-analysis involving 168 studies suggests that high stress levels may drive individuals to exercise more frequently. In other words, if you’re frustrated with someone at work, like Derek, you may find yourself pushing harder on the treadmill as a means to vent that frustration. Not only is this beneficial for your fitness, but it also helps you avoid potential conflicts with Derek in the office.

Nonetheless, stress can also lead to skipped workouts. “People who train in the morning tend to adhere better to a consistent fitness routine because the day’s stressors haven’t yet affected their energy levels,” Coxall notes. This insight suggests that morning sessions may be the best approach for safeguarding both your physical and mental well-being.

Does Timing Affect Strength and Size Gains?

When it comes to building strength and muscle size, the debate around workout timing becomes more intriguing. “Evening training often presents compelling advantages,” claims Coxall. Research indicates that individuals tend to exhibit greater strength output later in the day, likely due to the optimal hormonal balance at that time, including higher testosterone levels.

However, it’s not a clear-cut victory for evening workouts. A meta-analysis by Grgic et al. highlighted that while strength performance may peak later in the day, long-term muscle growth remains largely unaffected by the timing of workouts, provided that intensity and volume are consistent. So, although you might lift slightly more in the evening, the difference in muscle growth over time is minimal.

Risk of Injury: Timing Considerations

If you find yourself frequently injuring yourself and attributing it to your workout schedule, it might be time to reassess your approach. “Injury risk is influenced more by technique, load management, and overall fatigue than by whether you’re training at 7 AM or 7 PM,” notes Faithfull. While morning sessions might present challenges such as increased stiffness, proper warm-ups can mitigate risks.

The Lunchtime Workout: A Balanced Option

Lunchtime workouts are often underestimated. “For many professionals, this timeframe is the most reliable choice,” says Faithfull. “It’s less likely to be disrupted than evening plans, and it’s physiologically easier on the body than morning sessions.”

Coxall believes lunchtime workouts are the “sweet spot,” providing stable energy levels to power you through your day. Additionally, engaging in a midday workout can counteract the negative effects of prolonged sitting, with research illustrating increases in mood, productivity, and energy levels after exercise. A 2021 study titled “Sports Lunch Breaks, Vigor, and Creativity at Work” even indicated that a good workout can lead to enhanced cognitive function and creativity throughout the afternoon.

However, Faithfull cautions that the rush back to work might tempt you to compromise on your warm-up and form. If you opt for a lunchtime workout, prioritize quality over quantity.
