Set Minimal Goals
Good intentions often lead to unrealistic plans. Instead, for a week or month, choose a doable number of days to work out and stick to it. "Exercising 15 or 16 days a month will do you a ton of good, and it's really just every other day," says Baumeister. "If you aim for 15 but actually manage 20, you can feel great about how you're surpassing your goals."
As a reminder, always consult your doctor for medical advice and treatment before starting any program.
