Two weeks off: how to keep your training routine on holiday

Two weeks off, and you are already doing the maths on what you will lose. The honest answer is less dramatic than it feels: a fortnight rarely undoes months of work. The harder part is the return, and that gets decided before you leave the house.

What actually goes in fourteen days

Strength is the stubborn one. The evidence is strongest for trained people holding on to most of their strength across two to three weeks without lifting, and muscle mass barely shifts in that window. What fades faster is the feel of the movement, so the first set back seems heavier than the number on the bar says it should be.

Aerobic fitness is more delicate. It starts slipping after roughly two weeks of doing nothing, and the drop shows up most in people who were in the best shape, simply because they have more to lose. It also returns far quicker than it was built the first time.

The scales are the least reliable thing in the room. More salt, more carbohydrate, less training and a different fluid balance can add a kilogram or two with no change in body fat at all. If that number is what ruins your week, the same mechanics are unpicked in the piece on coming out of a deficit without panicking.

Decide before you pack

The worst version is the undecided one: trainers rattling around the suitcase, a low-level guilt every morning about not using them, and a return that feels neither rested nor productive. Pick one of three plans before you go, then stop renegotiating it daily.

A full stop. Zero planned sessions. This makes sense if you have trained without a break for six months or more, if something has been niggling, or if this is the only fortnight all year when you can genuinely switch off. Most bodies gain more from that than they lose.

Maintenance. Two short sessions a week, 20 to 30 minutes each. Cut the volume to about a third of normal but keep the effort per set close to what you usually do. Holding on to strength depends on intensity rather than amount, which is exactly why this plan is small enough to survive a holiday.

The minimum. One session a week plus walking. This is not a plan for progress; it exists so that training stays in your calendar. The same logic applies to any stretch when life scrambles the schedule, which is covered in the piece on keeping training going through a house move or a new job.

Twenty minutes and no equipment

If you have gone for maintenance, you need something that fits in a hotel room or a park. Five exercises, circuit style, two or three rounds, 60 seconds between rounds:

• Press-ups, 8 to 15 reps. Feet on the bed if it is too easy, hands on a table edge if it is too hard.
• Bulgarian split squats with the rear foot on a chair, 8 to 12 per leg.
• Single-leg Romanian deadlifts, 10 to 12 per leg, slow and with no weight.
• Band rows around a post or a door handle, 12 to 15 reps.
• Plank, three sets of 30 to 45 seconds.

A resistance band folds into a pocket and is the only kit worth the luggage space. Everything else improvises: a rucksack with water bottles for load, the stairwell instead of sprints, a towel round a post for pulling.

The holiday itself does a fair chunk of the work. A day of walking round a city easily reaches 12,000 to 18,000 steps, often more than a full week at a desk; how much that number means for you is covered in the piece on where the 10,000-step target came from. Twenty to thirty minutes of swimming, a hill walk or a bike ride will hold your fitness better than trying to rebuild your usual split in a bedroom.

Food and drink without counting every calorie

Weighing food on holiday rarely survives three days. Fix two meals instead and let the rest go. Breakfast with 25 to 40 grams of protein and a dinner built around a palm or two of meat, fish or pulses covers most of the day's needs, which means lunch and an ice cream can stop being a decision.

Alcohol is the quiet one. A cocktail often carries 200 to 400 calories, and it also flattens your sleep and your legs the next morning. This is a scheduling question rather than a ban: choose in advance how many of the fourteen evenings involve drinking, and the question stops being reopened by every waiter.

One bit of arithmetic that settles the nerves: half a kilogram of body fat takes roughly 3,500 calories of surplus. To genuinely gain two kilograms of fat in a fortnight you would need about 1,000 extra calories every single day. That happens far less often than the scales suggest on your third morning home.

Coming back, sleep and the first session

A holiday is the best chance you get to fix your sleep, because no alarm is standing in the way. If earlier mornings are the goal, shifting by 15 minutes across several days works better than one big jump, and the whole method is laid out in the piece on moving your sleep an hour earlier.

Book the first session back before you leave: an actual day and time in the calendar, not once I have sorted myself out. Run it at 60 to 70 per cent of your normal volume and leave two or three reps in reserve on every set. Testing maxes in week one buys nothing but soreness that costs you another five days.

It also helps to pack the bag the night before, because the first morning back is always the worst one. Those five minutes of evening prep are worth more than any amount of morning willpower. By the second week home, training usually feels ordinary again.

When to see a doctor

A few things on holiday are not travel fatigue. Pain and swelling in one calf after a long flight or drive, especially alongside breathlessness, needs checking urgently. The same goes for chest pain on exertion, fainting in the heat, confusion combined with stopping sweating, and diarrhoea with dehydration lasting more than two days.

And if something was already hurting before you left, two quiet weeks are a good moment to get it looked at rather than a good moment to wait and see.

The short version

• Across two weeks strength and muscle hold up well; aerobic fitness dips slightly and the feel of the movement dips most.
• Choose one plan before you travel: a full stop, two short sessions a week, or one session plus walking.
• For maintenance, cut volume to a third but keep the effort; 20 minutes and a resistance band will do it.
• Anchor breakfast and dinner with protein, decide your drinking evenings in advance, and skip the scales for the first few days home.
• Book the first session back before you go, run it at 60 to 70 per cent of normal volume, and test nothing.
