Five local Orangetheory Fitness studios have launched an ongoing partnership with a nationwide program called Sweat Angels in an effort to raise funds for various charitable organizations through Facebook “check-ins” made by gym patrons.

During the month of May, Sweat Angels will donate two days of prenatal vitamins for impoverished women through Vitamin Angels each time a gym goer checks in to a participating Valley Orangetheory Fitness studio before or after a workout.

The initiative, which kicked off in April, garnered over 800 Facebook check-ins, resulting in a donation of more than 400 minutes of autism therapy for children across the nation through The Autism Site.

“We’re thrilled to have partnered with Sweat Angels, because it not only allows our members to improve their health, but also to work out for a cause,” said Matt Kafora, owner of Orangetheory Fitness Scottsdale, Downtown Phoenix, Moon Valley, Arrowhead and Lake Pleasant. “This program is an authentic way to encourage our members to give back, and we look forward to our members doing their part and helping make the world a better place.”

For the month of June, 10 check-ins will equal one pair of shoes for a child in need through Soles4Souls. July’s focus is on H2Open Doors, which will provide 50 gallons of clean water to impoverished countries in need per every check-in. In August, check-ins will provide bricks to build schools in developing nations through an organization called  BuildOn.

Orangetheory Fitness is backed by the science of excess post-exercise oxygen consumption (EPOC). Orangetheory’s heart rate monitored training is designed to keep heart rates in a target zone that stimulates metabolism and increases energy. Led by skilled personal trainers, participants use a variety of equipment including treadmills, rowing machines, TRX Suspension Training and free weights. Participants can expect to burn anywhere from 500 to 1000 calories per 60-minute session. The result from this type of workout is the Orange Effect – meaning more energy, visible toning and extra calorie burn for up to 36 hours post-workout.

Participating studios include Orangetheory Fitness Scottsdale, Downtown Phoenix, Moon Valley, Arrowhead and Lake Pleasant.
