Read on to learn exactly how that fitness classes leave you with more muscle or better tone.
Bulky upper-body muscles might have hindered early humans who had to chase their prey across the plains, but it could help those who often had to climb trees to adjust their satellite dishes. That?s why the body builds muscle according mostly to use: do enough curls, and the biceps expand. As anyone who has experienced post-workout soreness could intuit, those curls are actually a form of controlled damage, making thousands of miniscule tears to the muscle tissue that beckon autoimmune cells to show up alongside testosterone and other hormones. The white blood cells help switch on satellite cells, which are similar to stem cells. Before they're activated, satellite cells aren't doing much?instead, they lie dormant around muscle fibers until they're called into action to repair torn tissue.
This isn't the only kind of cellular transformation at work in growing muscles. Long muscle cells, which contain several nuclei, can also begin to change type after a workout. Certain kinds of muscle fibers are equipped to handle brief bursts of effort but will quickly become tired if asked to do more intense work. These are the first to disappear as someone starts an exercise routine, as they're converted into fibers with more endurance. This principle is so dramatic that a sports scientist can generally tell whether someone is a professional athlete or a professional mattress model by examining a minute sample of muscle tissue.
Although they prefer to prevent infestations, the technicians at On The Spot Pest Control are trained to rout embedded insects and mammals while minimizing environmental impact. They follow the principles of Integrated Pest Management, a system that relies on catch-and-release animal-control practices when possible and promotes the reduced use of pesticides. Not content to glaze lawns with chemicals and call it a day, the team also creates barriers that change every season. In summer, it targets flying insects and spiders, and come fall it shores up defenses against rodents and back-to-school shoppers.
Mary and Shelly Withers let more than two decades of cooking together shine through in the kitchen, which fills with the crackling of hot oil and the slower contralto bubbling of stews and gravy as the two work in concert. Flanked by berry-colored walls, diners take seats at raw-wood tables and benches to dig into soul-food favorites such as baked mac 'n' cheese, fried catfish nuggets, and jerk chicken. Caterers laden with trays bound for weddings and other events rush past diners slowly working through cups of coffee and Mary's red velvet cake, which lets feasts end gradually, unlike picnics in wind tunnels.
Hiroshi Powell noticed he had a knack for weightlifting, so he swapped the weight machine in his mom's basement for a membership at a pro-level facility. There, Hiroshi began training with national powerlifting champions, learning the secrets of their technique while building friendships and cultivating his own carreers in powerlifting and bodybuilding.
The seriousness with which Hiroshi threw himself at his goals, and immersed himself in the fitness field, informs his approach as founder-owner of Chiseled Health and Fitness. "Chiseled," he says, "is not a social club or [a] cookie cutter commercial gym. Those are great for some folks, but not everyone." In place of the hundred-pound rubber chickens dead lifters find at other gyms, guests at Chiseled find a facility fully stocked with professional weight training and cardio essentials. Accented with red trim, the facility's white walls, black mats, and glossy hardwood floors offer a non-distracting environment in which Hiroshi and his three fellow personal trainers customize clients' workouts. Members also complete self-guided routines, and take CrossFit classes.
To begin their meals, diners at Baba Ghanoush BBQ can dig into the restaurant's namesake dish, swirling soft pita bread or the tastiest part of their shirt sleeve in the smoky, creamy, roasted eggplant dip. Moving on, it's tough to decide on an entree?the Middle Eastern menu is home to chicken, beef, and lamb kebabs, as well as falafel, labneh, and zesty tabbouleh salad. For dessert, try the bread pudding, or finish on a hot note with a cup of hibiscus tea.
Though the salon and spa is named after her, owner Kathy doesn't work alone. In fact, the hairstylist—who is also a trained massage therapist specializing in hot-stone and deep-tissue modalities—works alongside two other beauticians. Hairstylist Diane joins Kathy on the salon floor, where she showcases her apt knowledge of keratin treatments as well as constructing special-occasion hairdos. Together the duo reaches for Cures, GK Hair, and Paul Mitchell products as they create both classic and trendy hairstyles. Back in a private spa room, aesthetician Karina deep cleanses pores with custom facials. When Karina is out on the salon floor, she reaches for cosmetics to doll up customers for weddings, date nights, and parties at private clown-only clubs.
