When you are building a business, your body is part of your equipment. Long days, skipped meals and too much screen time can wear you down. The good news is that small, regular habits can make a real difference to how you feel.

Your body shapes your day

Tony Robbins puts a lot of weight on physiology: the idea that how you move, breathe and hold yourself affects how you feel. He suggests that changing what your body is doing is one of the quickest ways to change your state, and his writing also points to the basics of sleep and good food.

“Where focus goes, energy flows.”Tony Robbins, quoted on tonyrobbins.com, “How to discover your peak state”

For a founder, the practical lesson is simple. When you feel flat or stuck at your desk, try moving before you try pushing harder.

Fit movement into a busy day

You do not need a gym membership or an hour a day to get started. The NHS pages explain how much activity is recommended for adults and how to build up gradually. Ideas that fit around work:

Eat well around long days

Busy founders often skip meals and then grab whatever is quickest. A little planning helps. The NHS Eatwell Guide shows the balance of different food groups for a healthy diet. Some practical ideas:

Everyone is different, so if you have specific dietary needs or concerns, speak to your GP or a registered dietitian.

Do not trade away sleep

Late nights are tempting when there is always more to do. But tired decisions are rarely good ones. Try to keep a regular bedtime, keep work out of the bedroom, and switch off screens a while before sleep. The NHS Every Mind Matters site has tips on sleeping better.

Make it a daily discipline

Jim Rohn’s idea of simple daily disciplines applies to health as much as to business. A short daily walk does not change much in a week, but it adds up over a year. Start with one small health habit and attach it to your working day, such as a walk after you finish your morning admin.

A first-year example

Ravi runs a new web design business from his flat in Birmingham. He works long hours at his desk, often eats lunch at his keyboard and feels drained by mid-afternoon. He starts taking his first call of the day on a walk, makes lunch away from the screen, and keeps a water bottle on his desk. After checking with his GP, he starts the NHS Couch to 5K plan. He has not overhauled his life, but he feels more alert in the afternoons and more in control of his days.

Plan health into your week

Robbins’ Rapid Planning Method asks what result you want and why. You can use the same questions for your health. Rather than “get fit”, you might choose “feel energetic enough to finish my working day without a slump”, because you want to enjoy evenings with your family. Then pick one or two small actions, such as a daily walk and preparing lunches on Sunday, and put them in your calendar like any other appointment.
