Tony Petriello has joined the training team at Vitality Personal Fitness in Newton to lead a new class that combines fitness with boxing and conditioning. Petriello’s Total Body Knock Out is offered in small groups every Saturday at 10:30 a.m. A Golden Glove recipient and personal trainer for more than 20 years, Petriello fuses martial arts and boxing with a strength and conditioning repertoire to provide a challenging workout that improves speed, agility, hand-eye coordination, footwork, balance and endurance.

“Tony is energetic and fun, and he loves to help people train hard,” says Vitality owner and trainer Shayleen Pastick. “This is a great opportunity for our clients to get professional attention from a seasoned fitness professional.” Pastick says that Vitality fitness enthusiasts can enjoy safe, effective workouts without having to make a big financial commitment. Visitors can take their first class at Vitality for $20, and small-group training packages are also available.

“Anyone who comes to the Total Body Knock Out class should bring a water bottle and grab a free towel on the way into the studio because they’re going to need it.” advises Pastick. “If they have wraps and gloves they should bring those, too.”
