Whenever somebody tells me they have a busy schedule and therefore cannot progress, I call bulls***. Every year I board 100s of flights, covering several continents and multiple time zones and this never gets in my way. If I'm able to adhere to the plan while balancing these variables, so can you! Here are some great tips which I recommend you use when traveling to ensure this doesn't become an excuse.
Familiarize Yourself Before Traveling
The best way to succeed with anything in life is to prepare yourself, taking some time to familiarize yourself with the place you're traveling to is a great way to stay on track. This means learning about the local food, when places are open (many places around the world have different opening times), what facilities the hotel has, which gyms are available and anything else relevant. By doing this you can prepare before you arrive, factoring in any obstacles which would otherwise derail your efforts.
Small things like getting yourself bottled water on arrival is essential, drinking tap water is never a good idea, especially in a foreign country which your gut is not used to. This alone could make you feel unwell and kill progress. You cannot over prepare before traveling!
Adapt Your Diet Strategy
It might be smart to adapt your diet if you're traveling a long distance because of time constraints or poor food quality. For example, controlled intermittent fasting is a great option when traveling because it means you avoid eating junk in airports and the plane. It also means when you reach your hotel you will have the opportunity to get the right food and make up for the calories you have not consumed. Fasting is just one example of many and should only be used if it is appropriate for your current goal. In this context I am just trying to open your eyes to the fact that new strategies can be used for specific circumstances, to support further progression.
Create a Schedule
Although it may not be the same as your conventional schedule when home, it is important to determine a structure for your time away. This prevents time being lost and obstacles derailing your ability to stay on track - those who travel with no structure will inevitably fail to remain consistent with training and diet.
