Phil Coles said there are plenty of companies providing online exercise classes that could help compensate for a lack of gyms or home exercise equipment. Several Celtics players have said they do not have home gyms and depend on Coles’s script to exercise. “You can develop your own version of these body-weight training programs, push-ups and chin-ups, and dips, and a number of things you can do in your space,” he said. “It’s just about making sure you’re consistent with it and prioritize and program so you have a routine of getting it done.”
