Best time to work out and do you skip a day if you're sore?

Working out works best when you fit it in your schedule. I have the most energy later at night, so that's when we go.

I workout on days I am sore, but define sore? If my ankles are killing me then I will workout a different part of my body. Don't make working out another job, just do it as much as you can/ feel you can.

Define sore. Bit of DOMS or stiffness, I work through it. Tendon or ligament pain, absolutely not.

• Your circadian rhythm is a 24 hour cycle of biological activity set by your internal clock. Your sleep-wake cycle is one of many systems influenced by your circadian rhythm.
• Your hormonal milieu, gene expression and core body temperature have a circadian rhythm. Together, they result in peak physical condition to train and recover in the late afternoon to early evening.
• The best time to work out is generally between 14:30 and 20:30 h if you have a regular sleep-wake cycle.
• You can determine the optimal time to train by monitoring your maximum resting heart rate and training performance.
• If you can’t train when your body is primed to do so, supplement with caffeine pre-workout and schedule your workouts when you can always train.

There is a sign in my gym that says people who work out in the morning are more likely to stick to it. Especially if you have kids etc. I know that by the time I get home, cook dinner, help with homework etc I'm not in the mood to lift weights!

That said: Do it whenever you can. Whatever time actually fits your schedule the best is the best time.

Try and stick to the plan. Some soreness (Delayed onset muscle soreness, or DOMS) is to be expected at first when you start a new routine. Stretch well, and try to work through it. Even a bad workout is better than no workout. But if you are truly too sore or have a pain (rather than a general soreness) do take a rest, or work a different part of the body. If you are on a reasonable weight lifting plan, for example, then it won't have you doing the same muscles on adjacent days.

In the past, (I have had to lose 60 lbs after each of my first 2 pregnancies) I noticed that I always had better results working out first thing in the morning before you eat. Working out in the afternoons is just as good im sure but I heard on an old Jillian Michael's workout video that working out first thing in the morning will kick start your metabolism so once you do eat (wait 30 min after the workout) your metabolism is already running and burns fat easier. Hope this helps but ultimately doing anything at anytime is better than nothing at all!

Workout whenever you feel like it...it doesn't matter.

Your fitness regimen should include rest as well as days of varying intensity...you don't have to go balls to the wall 7 days per week...in fact that's a recipe for just getting injured and then having to sit on your *kitten* for several weeks. Ask me how I know...

If you're doing resistance training, your training days should either be splits or you should do full body 3x weekly every other day. You do not want to train the same muscles/muscle groups on consecutive days...if you are, you're basically wasting your time as the benefits of lifting/resistance work come with rest. Exceptions would be working muscular endurance/muscular stamina...but actual strength and physique work requires rest.

A typical, well rounded general fitness regimen would have you doing roughly equal parts of strength/resistance to cardio work. Most often people do these on alternating days...i.e.:

Monday - 45 - 60 minutes cardio (Go hard)
Tuesday - Strength/Resistance
Wed - 45 - 60 minutes cardio (Steady Tempo)
Thurs - Strength/Resistance
Friday - 45 - 60 minutes cardio (Steady Tempo/Recovery)
Saturday - Strength/Resistance
Sunday - Rest

That's just pretty basic, general fitness...from there, your personal fitness goals would dictate more or less or intensity of various bouts of exercise.

Being newish to fitness you may want to start out slower and include an additional rest day. I would also suggest to listen to your body. For the most part I get in 6 workouts per week similar to the above but there are someday where my body just isn't going to do it...and it's more than soreness...in those instances I do whatever I need to do.

This week for example I am dealing with a nagging foot issue that comes and goes...I'm not going to be able to get in all my rides this week because of it...so I'll just rest and not push it, that way by next week I should be right as rain...pushing it could end up knocking me out of the saddle for weeks instead of just a couple days off.

i start at 4am, and pain or pleasure,
i go hard 7 days a week, 2 to 3 hours cardio a day.

Workout any time you like working out at.

I'll do anything from a 9:30am to heavy lifting or punch bag work at 12:30am sometimes! (The benefits of having your own setup away from people ).

Normally weights workouts between 1pm-9pm.
I try and make sure I've had food before weights or serious cardio workouts. Don't mind not eating before a lighter cardio - but evidence has shown I really do need food before proper cardio; difference in eating and not eating before a fell run was very apparent with 2.2 miles further done in 5 minutes extra with nutrition!

As far as soreness goes - if it's going to detract from the workout it's self, might consider delaying it, but usually don't worry.
I find doing the same things I fairly quickly stop getting DOMS, even when working out with weights to limits - maybe less so for cardio, but been able to bash out decent lengths on adverse terrain and not notice too much recently.

Morning or night is your choice. Soreness will go away with time as you adapt to the new activity. Skip a day if you think it'll make you worse or prone to hurting yourself due to any limited range of motion.

A better idea is to make sure you're easing into your exercise, so that you're not getting too sore right away.

The best time to workout is whichever time you'll be able to be most consistent.

That being said, there may be a slight advantage to workout timing depending on what it is you do. Hormonal factors favor weight lifting later in the day (afternoon/evening.)

I don't skip a day if I'm sore from DOMS, but I don't hesitate to skip a day when I can tell I'm too beat up to get a good workout. When the warmup weights feel heavier than normal, I call it a day. When it happens 2-3 times in a row, I deload (unless I have programmed reloads.) If your soreness is not DOMS definitely skip a day.
