Although there are infinite paths to shredding fat, EverFit considers running a key part of an optimal fitness program for anyone looking to lose fat. Nothing else burns fat so efficiently or conveniently. In 30 minutes, you can complete a serious workout that pushes you closer to your goal. That 30 minute workout raises your metabolism for the next day and helps you sleep better at night, which further improves metabolism.
Pairing a strong running program with weight training yields the best of both worlds, as the increased muscle mass from weight lifting burns up more calories around the clock as well. This is the approach we take with EverFit trainees and the results have been incredible.
