Weighted clothing, from leggings to shirts, is the latest trend in fitness gear. Brands are now embedding small weights directly into apparel, promising an easier way to add resistance to workouts. But do these products deliver tangible results, or are they just another hyped-up gimmick? Experts weigh in.
The Limited Benefits of Minimal Weight
While weighted clothes feel heavier than standard gym wear, the added resistance – typically just half a pound to three pounds – is unlikely to significantly impact strength or endurance gains. Exercise physiologist Rachelle Reed, PhD, at Therabody, points out that the weight fluctuations people experience daily (through hydration, digestion, etc.) often exceed these incremental increases.
“The body fluctuates more weight in a day than this,” Reed explains. “These clothes aren’t providing a stimulus strong enough to drive meaningful physiological change.”
Current research supports this skepticism. Studies on weighted vests (a more substantial form of resistance) show only minor improvements in muscular strength, bone density, and calorie burn – and those benefits require consistent, high-intensity use. A Wake Forest study found slight bone density gains in elderly participants (average age 66) wearing vests at 20% of their body weight for eight hours daily. Another small study showed modest calorie expenditure increases in a similar demographic after six hours of vest use.
Where They Might Help: Muscular Endurance
Weighted clothing could offer some value in high-repetition workouts. For disciplines like Pilates or barre, the added weight might feel comparable to using ankle or wrist weights, providing a slight but noticeable challenge. Reed suggests that in low-weight, high-rep exercises, even a small increase in resistance can make a difference.
However, there is no specific scientific data to confirm this.
The Psychological Edge
Perhaps the most significant benefit of weighted clothing is psychological. They can reignite enthusiasm for exercise by adding novelty to routines. As Shannon Ritchey, DPT, founder of Evlo Fitness, notes, “These products get people re-engaged with activity.”
If you’re looking for a fun way to break out of a fitness rut, weighted clothing might provide that extra push. The risk of injury from such minimal weight is negligible.
The Bottom Line
Weighted clothing isn’t a substitute for proven training methods like resistance lifting. If you’re serious about building strength, size, or endurance, stick with established techniques. These garments are unlikely to produce significant physical changes, but they might be a harmless (and potentially motivating) addition to your workout wardrobe.
