Jillian Michaels on Two Hours of Exercise Weekly: recommends

Jillian Michaels prescribes a minimum of two hours of exercise per week — for example, five 20-minute or four 30-minute sessions — with an upper ceiling of about six hours weekly, per her own site. She frames the two-hour floor as an achievable baseline rather than an elite training load.

Her stated reasoning is sustainability: short, consistent sessions beat sporadic long workouts, and most people can fit five 20-minute sessions into a week. She presents the range as the practical dose needed to support her nutrition framework without demanding a bodybuilder’s schedule.
