Holiday schedules have a way of throwing routines off track, and exercise often takes a back seat. Between travel, social events, and endless tasks, finding time for a full workout can feel impossible. Shifting the focus to short, efficient sessions makes it easier to stay active even on the busiest days.
Research supports multiple approaches—from structured high-intensity workouts to brief bouts of vigorous activity—that help maintain strength and fitness without requiring hours in the gym.
High-Intensity Workouts That Save Time

Short workouts can deliver impressive results when they involve near-maximum effort. High-intensity interval training (HIIT) stands out as one of the fastest ways to improve aerobic fitness.
A well-known 1990s study introduced a powerful format: a 4-minute session built around repeated rounds of 20 seconds of intense effort followed by 10 seconds of rest, performed five days a week for six weeks. Participants achieved greater aerobic gains than those completing hour-long moderate sessions.
HIIT remains useful during hectic holiday days because it demands little time yet significantly boosts endurance and heart health. A few minutes of structured intensity can outperform much longer workouts when consistency is hard to maintain.
Short “Exercise Snacks” for Busy Days
Some days allow even less room for planned workouts, and that’s where tiny bursts of vigorous movement—often called exercise snacks—make a difference. Research in 2023 involving more than 22,000 adults who did not exercise reported that just 3.5 minutes of vigorous activity per day was linked to a reduced risk of cardiovascular disease in women.
Another analysis that included people who intentionally exercised found that these short bursts were tied to a 20 percent lower risk of heart attack and stroke for men and women.
These intense moments can appear naturally throughout the day, including:
1. Running to catch a bus
2. Carrying heavy grocery bags
3. Climbing stairs quickly
4. Rushing through an airport with gifts
A 2019 study added more insight, showing that going up three flights of stairs vigorously, three times a day, three days a week, improved a key measure of cardiovascular fitness by about 5 percent after six weeks.
Steady Steps for Low-Intensity Movement

Not every approach needs to be high-intensity. Simply keeping up a consistent step count is an easy and effective way to stay active throughout the holiday season.
Keeping Progress in Perspective
Holiday interruptions don’t wipe out progress quickly. Research shows that noticeable declines in muscle strength usually develop after two to three months without training, while aerobic conditioning tends to fade after about a month. Prioritizing activities that raise heart rate—such as quick, vigorous bursts of movement or fast-paced walks—helps preserve endurance during this period.
A packed schedule still allows room for simple strategies. HIIT sessions, short vigorous “exercise snacks,” and maintaining steady daily steps offer efficient ways to stay active with limited time. These options support cardiovascular health and help maintain overall fitness until regular routines resume.
Keeping movement flexible and intentional allows fitness to stay on track throughout the busiest part of the year.
