Bulk up to succeed where others have failed with today’s Groupon: for $10, you get a one-month membership (a $95 value) and one personal-training session (a $75 value) at Five Points Fitness in Corte Madera (a $170 value).

The newly renovated 17,000-square-foot facility at Five Points Fitness welcomes exercisers with a gleaming fleet of machines and myriad classes. Rows of television-mounted cardio equipment allow members to simultaneously increase stamina and infomercial endurance levels.
