How important is sleep for making progress?
Direct answer
Very. Sleep affects far more than simply how tired you feel the next day.
Explanation
Your sleep can influence your recovery from training, physical performance, concentration, mood, appetite and motivation. All of these can then affect how well you're able to train, eat and recover consistently.
For example, if you're regularly sleeping poorly, you might find it harder to perform at your usual level in the gym, recover between sessions or make the nutritional choices you'd normally make when you're well rested.
That means sleep is worth considering when progress starts to slow. If your strength has plateaued, your energy has dropped or you're finding your normal routine considerably harder to maintain, I'd want to know what's happening with your sleep alongside looking at your training and nutrition.
That doesn't mean every bad workout or difficult week can be blamed on sleep. It's one part of the wider picture.
How to apply this
Treat sleep as part of your training and recovery rather than something completely separate from it.
Look at both how much you're sleeping and the quality and consistency of that sleep. If there's room for improvement, simple changes such as keeping a more consistent routine, giving yourself enough time to sleep and looking at habits that regularly interfere with it can make a difference.
You don't need perfect sleep every night to make progress. But if poor sleep has become the norm, it's worth addressing rather than trying to solve everything by changing your training or diet.
