A Month in a Weighted Vest: Unexpected Health Benefits

Wearing a weighted vest for a month, a practice gaining traction among fitness enthusiasts and celebrities alike, yielded surprising health improvements for one writer. The vest, which resembles a bulletproof vest, adds resistance to everyday movements, increasing energy expenditure and placing greater demands on the heart and muscles.

Initial skepticism gave way to a commitment to a four-week trial. Before starting, baseline health markers were recorded: weight at 12st 12lb (81.8kg), a BMI of 28.1, and body fat at 4st 13lb (31.2kg). Concerns about high cholesterol, with a total reading of 6.18mmol/l and LDL of 3.76mmol/l, were also a key focus.

The vest, which can range from £20 to several hundred pounds, comes in various weights. Starting with a 3kg vest, the author found the weight distributed evenly, making it less cumbersome than anticipated. The initial use focused on household chores, gradually increasing to six hours a day. The added weight was noted to significantly raise heart rate, challenge balance, and encourage a taller posture.

Experts suggest building up to carrying approximately 5% of body weight. James Davies, an osteopath and fitness trainer, noted that weighted vests are a tool to enhance training, not a replacement, stressing that the increased load on muscles and bones can improve overall fitness. Professor Sanjay Sharma, a cardiology adviser for the Football Association, highlighted that such strength training can improve lean body mass, reduce visceral fat, and enhance bone mineral density, potentially lowering risks of all-cause mortality.

Gradual Progression and Noteworthy Changes

As the trial progressed, the vest was incorporated into daily walks, starting with 15 minutes and increasing gradually. The intensity of these walks moved from 'moderate' to 'hard' on a fitness tracker. In the second week, a move to a 5kg vest presented initial discomfort, particularly for a pre-existing shoulder issue. Following advice to ensure proper fit and listen to the body, the pain subsided as the body adapted.

By the fourth week, using a 6kg vest, the results were measured. Weight loss was 2kg, but muscle mass increased from 48kg to 50.6kg. The BMI decreased to 27.6, now within the desirable range. Visceral fat also reduced. Most significantly, total cholesterol dropped to 5.28mmol/l, and LDL to 3.01mmol/l, nearing optimal levels. The writer's biological age was estimated to have decreased by nearly a decade, with improved breathlessness during physical activity.

Considerations and Suitability

While the benefits were substantial for the trial participant, experts caution that weighted vests are not suitable for everyone. Giuseppe Salustri, clinical director of The Physio Box, advised individuals with osteoarthritis, inflamed joints, or hip, knee, or ankle injuries to avoid them, as the added load could exacerbate symptoms. He also suggested that those already carrying excess weight or experiencing knee pain might not benefit from increased load.

The vest's accessibility and ease of integration into daily routines were highlighted as key advantages. The author concluded that for individuals with time constraints, the weighted vest offers a practical method to increase the intensity of everyday movement and enhance strength and fitness, despite potential initial public surprise.
