Episode 1: Prepare yourself for Week 1 with Autumn and the cast with this all-access look inside the making of 80 Day Obsession. Six different workout themes (e.g., booty, legs, etc.) are repeated every week, but Autumn changes how you do them each time, so no two workouts are ever the same.

Resistance loop malfunctions. Mic drops. Water bottle mishaps. A few stumbles won't stop Autumn and the cast from crushing week two.

The cast is starting to find its groove as members begin to see and feel changes in their bodies—especially in their booties. Calie surprises her castmates with a homemade, post-workout treat to help optimize their recovery.

As Phase 1 comes to an end, cast members share the positive effects that their new eating and exercise habits are having on their workouts and lives. Plus, Beachbody CEO Carl Daikeler stops by the 80 Day Obsession set to recognize an impressive milestone.

New moves in Phase 2 get the cast excited. They’re also motivated by the extent of their transformations—some are even noticing clearer skin. Glowing, happy faces!

The cast experiences its first refeed day, and share in all the goodies. But that’s not the only treat; Autumn surprises the cast with a special gift.

Having reached the halfway point, Autumn and the cast discuss their experiences so far, and bond over their challenges and achievements. Confidence is growing as cast members find motivation and inspiration in each other on and off the set.

It’s all about celebrating the small victories as Phase 2 finishes, and what better way for cast members to do that than to showcase their gains? An energy boost from the second refeed day also leads to some on-set antics.

With Phase 2 complete, the cast is excited to see the results of their weigh-ins, measurements, and progress photos. Now the final phase begins, and they must rise to the challenge of even tougher workouts. Concerned that some of the cast is feeling rundown, Autumn discusses the importance of maintaining healthy habits beyond diet and exercise.

The exercises are getting harder, meal prep is getting easier, and the third refeed day is finally here! The cast is encouraged by the progress they've made, but realize that they need to maintain their momentum and motivation into the final weeks of the program. Autumn explains the importance of staying focused--especially on weekends.

Looser clothes, greater endurance, and noticeably firmer booties help keep the cast motivated and pushing hard into the final three weeks of 80 Day Obsession. A rare look behind the camera also catches Beachbody's top fitness expert at work, and Autumn discusses the benefits of supplementing with Beachbody Performance products.

It's the last week of Phase 3, and the cast has mixed emotions. They're thrilled by how strong and fit they've become, and sad that the end of the program is in sight! But it's not finished yet; they still have to make it through Peak Week, during which they'll face their toughest nutritional challenge yet.​

It's Peak Week! Which means it's time for the final shred. As the cast cuts carbs and powers through Autumn's handpicked workouts, they reflect on how far they've come since day one, and how they plan stay in shape after day 80. It's always important to know what your next step is, and after this week, you'll be ready for any program on Beachbody on Demand.
