I am not a fitness expert. I am just a normal guy working in IT who got fed up feeling out of breath walking up two flights of stairs. But I accidentally ended up doing the perfect experiment on morning vs evening workouts: which one is better?
Here’s what happened. My company relocated office buildings last year, and bam! My commute took a major leap from 15 minutes to one hour each way. I needed to completely reschedule my gym time. For nine months, I was a morning person. Then my schedule changed again, and I became an evening workout person for another nine months.
Same gym. Same goals. Totally different experiences.
5:30 AM Was Brutal (But Worth It)
I hated getting up before sunrise. I’d hear my alarm sound and start negotiating with myself right away. “Maybe I’ll go tomorrow.” “It’s cold outside.” “I didn’t sleep well.”
But, weirdly enough, when I finally got to the gym, something strange happened. I felt as if I could conquer the world afterwards. My colleagues began remarking that I seemed more alert in meetings. My wife commented that I was less grumpy in the evenings.
The hunger thing was real, though. Working out in the morning on an empty stomach made me feel too shaky if I was doing heavy lifting at the gym. I’d have these episodes where my vision would go a little fuzzy. Not fun when you’re holding a barbell over your head.
My trainer, Stephanie, suggested I try it anyway for fat loss. She mentioned something about burning stored fat when your stomach’s empty. I figured I’d give it a shot.

Evening Workouts Felt Like Cheating
When my schedule flipped and I began going after work, it was like switching from difficult mode to easy mode. I could lift heavier weights. My running pace was faster. I wasn’t plagued by thoughts of passing out in the middle of a workout.
It makes sense, right? I had been eating all day, so I had plenty of fuel to burn. Besides, I’m more alert at 6 p.m. than I ever was at 6 a.m.
The problem was motivation. I’d already spent the day dealing with spreadsheets and conference calls; I didn’t particularly want to go sweat for an hour. My couch was calling. Netflix was calling. A cold beer was definitely calling.
I probably skipped evening workouts twice as often as morning ones. Just being honest here.
What the Science Nerds Say
I wondered if my experiences matched up with real studies. It turns out scientists have been studying this stuff for years.
One study I came across said people burn approximately 70 per cent more fat when working out on an empty stomach. That would make sense as to why I had started seeing an ab definition during my morning workouts, despite feeling weaker.
Another study demonstrated that your muscle power is highest in the evening. Something about your body temperature being higher and your joints being more flexible after moving all day. That confirmed my own feeling of being able to lift a little more weight in the evening.
For women specifically, morning workouts might be better for losing belly fat. The research suggested that women who worked out between 7 and 9 AM lost more abdominal fat than evening exercisers. Is it better to work out in the morning or at night for women? Based on that study, maybe mornings.
But here’s the kicker: other research showed that workout timing doesn’t matter much for overall weight loss if you’re consistent. Consistency beats timing every single time.
My Sister’s Take (She’s a Physical Therapist)
I asked my sister Lauren about this because she actually knows what she’s talking about. She works at a rehab clinic and sees all kinds of people trying to get back in shape.
“The best time to exercise, morning or evening, is whatever time you’ll actually show up,” she told me. “I’ve seen people obsess over optimal timing while skipping workouts three times a week.”
She had a point. During my morning phase, I was more consistent but weaker. During my evening phase, I was stronger but less consistent. Neither approach was perfect.
When is the Best Time to Work Out to Lose Weight?
Based on my experiment and what I’ve read, morning workouts might have a slight edge for fat loss. Something about fasting overnight and then burning stored fat for energy. I definitely got leaner during my early morning phase.
But evening workouts were better for building strength. Is it better to work out in the morning or evening to gain muscle? If I had to pick based on my experience, I’d say evenings. I hit personal records on my bench press and squats during that phase.
In addition, paying attention to post-workout nutrition can make a noticeable difference in how your body responds to training. A simple, high-quality protein source with minimal ingredients can support muscle recovery and fit easily into both morning and evening routines without adding unnecessary complexity.
The Best Time to Work Out to Lose Belly Fat
This one’s interesting because it’s where I saw the biggest difference. My morning workout phase was when I finally started seeing my abs. It could be a coincidence, but the research backs this up, too.
Working out in the morning on an empty stomach seemed to target belly fat specifically. I wasn’t doing anything different besides timing and eating schedules, but that’s when the stubborn fat around my midsection started disappearing.
What I Actually Do Now
These days, I mix it up. Monday, Wednesday, and Friday mornings for cardio—usually 30 minutes on the bike or treadmill. Tuesday and Thursday evenings for weights. Saturday morning, for whatever I feel like doing.
Morning vs. evening workout research is fascinating, but real life is messier than research studies. Some days I oversleep and miss my morning session. Some evenings I’m too beat from work to lift heavy. That’s normal.
The key thing I learned? Having a backup plan matters more than having a perfect schedule. If I miss my morning cardio, I’ll do 20 minutes after dinner. If I can’t make it to evening weights, I’ll do pushups and bodyweight stuff at home.

Bottom Line
Here’s what 18 months of accidentally experimenting taught me: both morning and evening workouts work, but they work differently.
Mornings are more consistent and better for fat burning and starting your day full of energy. Performance is better in the evening, and so are strength gains. Plus, it’s easier to find the time for longer workouts in the evening.
But the most important factor? Choose a time you can maintain over the long haul. A mediocre workout that happens consistently beats a perfect workout that happens sporadically.
Don’t overthink this. Try both if you can. See what fits your life, your energy levels, and your goals. Then stick with it for at least a few months before deciding if it’s working.
The worst workout time is the one where you don’t work out at all.
