Cardio in the am or pm?

Options
Hi guys, I just wanted to know of your experiences on doing cardio on an empty stomach first thing waking up into morning or doing cardio in the evening. I have heard both pros and cons and just wandering what do you guys think. Any suggestions? Thanks dave

    Personally, cardio is best for me first thing in the morning on either an empty stomach or a cup of coffee. When I run later in the day, it usually makes me feel a little nauseous, even if it's been a few hours since my last meal.

    I don't think it makes that big of a difference... I might do cardio once a week or so unless I am training for something like a spartan race

    As an insomniac, I prefer to do cardio either in the morning or during my lunch hour. Working out at night, be it cardio or lifting, tends to interfere with my sleep.

    ETA: If it's a morning session, I don't eat beforehand. If it's a midday/afternoon session, it's usually 1.5-2 hours after I've eaten.

    I prefer at least 2, preferably 4 hours from when I last eat until I do cardio. Otherwise its like a bowling ball in my belly. I've never had issues running fasted in the mornings and rather enjoy that setup. Try whichever works for you. Everyone is different.

    If I haven't eaten at least an hour before, my heart rate will be sky high and I'll feel extremely weak. Oh yeah, my hands also start shaking. And I might feel like I need to throw up.
    My cardio tends to be quite intense (Bodycombat), but for me to attend 8.30 class, I'll have to have a banana and skyr (dairy product) before 7.30 at latest.

    Weekdays, I perfer afternoon. When I did ride in the morning, I perfer to be fasted. Stop during it because I can't stay warm even in summer (start time between 6:30-7:00). Rides average 90 minutes.

    On weekends, I perfer morning and eat before. I normal up before 6:00 but don't start riding until 8:00. Weekend ride are normally 3+ hours on Saturdays and 2 on Sundays.

    I think it depends on if you are a morning person or a night owl. I prefer not to know what a sunrise looks like, so I do late workouts. I'm also one of those odd sorts that likes a big meal before I workout. Being hungry has never gotten me through the last mile or one more set.

    If we're talking impact on weight loss........................it doesn't matter. If we're talking on what works best for an individual, then only the individual will know.

    I split my cardio up with a jog/walk in the morning and then either a walk or bike ride later in the afternoon.

    It's personal. Try at several times and see what/when YOU like. Then go with that. Kinda like asking which is the best way to cook a steak. I like mine rare, others medium rare, others medium etc.

    There is no One True Way(TM) on this.

    Personally my midweek runs tend to be in the evening, generally 6-10 miles, sometimes up to 15. I'll snack at about 1600-1700 before that.

    At weekends I'll do my longer runs, generally back to backs from 13 miles upwards, so I'll generally eat an hour or so before heading out. That gets me beyond the 90-110 minute point, where I find a bit of fuelling can be helpful.

    In the morning your Glycogen is supposedly less so you get more bang for your buck. I do Steady State right when I get up. Takes about 10 minutes to kick in then I feel great!

    It's personal preference...there are some benefits in regards to endurance and performance when you train fasted at times. I do some of my training fasted and other times not.

    In regards to losing weight (fat), it makes no difference.

    If your doing low intensity cardio you preserve glycogen stores and burn primarily from fat stores in the mornings. This type of cardio is considered to be the "best" type to perform in a fasted state (in the early morning) or depleted state (post workout). In my experience, even with moderate or high intensity cardio, early morning fasted state cardio works best for me but really it's a question of preference & everyone has their own opinion. Just do what you feel works the best for you...

    In regards to the OP, the best time to do cardio (or any workout, for that matter) is whenever you'll do it most consistently. Workouts you do at a time that fits into your schedule are better than missed workouts from trying to squeeze them in at a supposed "optimal" time. Personal preference is the most important consideration.

    The site you referred me to was only a blog - or basically one man's opinion... Although well written and had some good information he says only that there is no evidence that it does work and he has zero factual evidence that it doesn't. I disagree with his hypothesis but respect it. There are several studies that show fasted state and depleted state cardio burns more calories. I never stated that it burns fat as no cardiovascular exercises actually burn fat - only raises metabolism and allows you to be in a caloric deficit state so you lose weight. There are many other factors that go into fat loss...
    I just let the OP know what worked best for me as he asked & you parroted my main advice that personal preference is the most important consideration.

    I think you missed all the links to studies supporting that opinion.

    Read through it again. See all the words in blue letters? Those are links. Links to studies. Studies are sometimes considered evidence.
