The document discusses circuit training at the Enfield Senior Center. It implemented circuit training two days per month in December and saw good participation. The next step is to decrease rest time between exercises to further increase benefits. The March circuit included Gene Vaillancourt, Gerry Ouellette, John Dubois and Betty Maloney participating. High intensity interval training is recommended for those stuck at a weight loss plateau, as it can burn an hour's worth of calories in only 20 minutes. Circuit training involves working all major muscle groups with high repetitions, low resistance, and short rest intervals to improve muscle tone and cardiovascular fitness.
