Is it okay to exercise after a poor night's sleep? Yes, say experts – but here's what you need to know

We've all been there: after a rough night's rest, you're tired and irritable. Your brain feels foggy and you're drowsy and sluggish.

All you want is to recharge your body and mind, so you ask yourself: "Should I skip my workout and try again tomorrow?"

Some research suggests that it's not really worth it, and that a lack of sleep can negatively affect your athletic performance. But the latest research from scientists in Australia suggests that you can successfully get in a workout after a poor night's sleep - all you have to do is stick to these two tips: exercise soon after you've woken up, and avoid complex skills training, which require high levels of co-ordination and control (such as serving in tennis).
