In addition to hard-to-find items like toilet paper and Clorox wipes during the pandemic, dumbbells have been an unexpected addition to the list. Like most at-home-fitness items, demand for dumbbells has increased dramatically in recent months, leaving sellers in short supply and Americans without free weights. According to Vox, part of the shortage has to do with supply chain delays from early shutdowns in China, where 95% of dumbbells are manufactured. The dearth of the weights was compounded by lack of inventory from sellers, like Dick's, Target, and Amazon, that usually stock up on fitness products at the beginning of the year and were, of course, unable to predict the pandemic-related surge. Demand for Peloton has skyrocketed during the pandemic, so much so that the company has struggled to keep up as quarantined Americans clamor for the stationary bikes. In the first quarter of 2020, sales increased by 66% while subscribers to the Peloton app increased by 94%, Business Insider's Mary Hanbury reported. However, those looking to get their hands on a Peloton before winter sets in should place an order sooner rather than later — the bikes are currently on weeks-long backorder, even after the company announced it was increasing production in June. Americans were hard-pressed to find bicycles early in the pandemic, as heavy demand led to wide-scale shortages around the country. Sales at bike shops saw record levels, with some increasing by nearly 600%, Business Insider's Jessica Snouwaert reported. With gyms shuttered, consumers began to buy at-home fitness en masse to create their own fitness centers at home. In addition to skyrocketing growth of Peloton bikes, companies like NordicTrack and Nautilus that specialize in products like treadmills and rowing machines have reported record sales. Colleen Logan, vice president of marketing at Icon Health & Fitness, the parent company of NordicTrack, told Vox that the company experienced crazy demand, with sales increasing by 600% in May. Though gyms have slowly started to reopen across the country, they're not the same fitness centers we once knew them to be. Many companies are enforcing strict social distancing and safety protocols, including limiting capacity, requiring the use of masks, and taking the temperature of gymgoers before entering the facility. In regions where gyms are still prohibited from opening, some gym owners have covertly started opening their doors on the sly in defiance of state policies. According to NPR's Planet Money, the speakeasy gyms are part of a growing culture of the COVID-19 Prohibition era, and many of these secret gymgoers are not adhering to protocols like social distancing. The longer gym shutdowns last during the COVID-19 prohibition era, the more likely people will evade them, NPR's Greg Rosalsky wrote in a recent Planet Money newsletter. And keep in mind it's summer. Come this fall and winter, millions of workout fiends in cold climates could have fewer legal options to exercise. Speakeasy gyms could have an even greater demand.According to findings from Sensor Tower, fitness app downloads increased by 47% year-over-year in the second quarter of 2020, reaching a total of 656 million health and fitness apps downloaded during the period.The top growing app was Strava, which Sensor Tower found had a particularly sharp rise with a record 3.4 million users in May, an uptick of 179.2% from January 2020. Many popular boutique fitness chains ranging from Rumble to CorePower Yoga have taken their classes online, offering some classes for free to stream directly from home, and other classes at a premium.In addition to hosting virtual classes, personal trainers have started to convene small groups for socially distant outdoor fitness classes in an effort to keep the blood pumping and still make an extra buck. Some are even getting extra creative with the outdoor fitness trend, including exercising in socially distant bubbles. Despite early dispute over whether running outside was permissible during the pandemic — and if it was best to be done with or without a mask — Americans are dusting off their running shoes and hitting the pavement during the pandemic. With offices shuttered and many Americans working remotely, they've swapped out their work attire for comfortable clothes, including athleisure and athletic apparel which has seen a significant boom in sales in recent months. A recent report by the consumer intelligence platform CivicScience found that 20% of American adults have purchased leisurewear since the beginning of the outbreak.
