I am absolutely LOVING 80 Day Obsession!!! I’m just starting week 7 now but I have to update you on how Phase 1 went before we move on! I still owe you a race report form Rock n’ Roll Los Angeles too – look for that in the next couple of days.
80 Day Obsession Phase 1 Review
Phase 1 of 80 Day Obsession is 4 weeks long, with six workouts per week. Each workout is different so there are 24 workouts total (plus a foam rolling routine and a stretching routine).
First, I have to say what a HUGE difference there is between LIIFT4 and 80 Day Obsession. The vibe, the pace, the moves… everything. After getting very used to (and loving!) LIIFT4, the first week of 80 Day Obsession felt slow and honestly a little easy to me! I was a little skeptical. The moves themselves are actually more complex, but it took Autumn time to explain them which meant the transitions were slower at first and it took a week or two for me to figure out which weights and bands I ended to get the most effective workout (except for Legs, I felt it after that one!). Also, the format of the workout in 80 Day Obsession changes every week, and I found that the first week of each round the format is the easiest and the third and forth weeks are the hardest. So..if you’ve done one or two weeks of this program and are skeptical, my advice is NOT to give up – it gets so much better! I promise!
After week 2, I was totally hooked and LOVING this program. The hour workouts are still hard to get used to but I’m super challenged by the end. I love Autumn’s vibe and her positivity and the way she motivates me to push harder and lift heavier. She has a great way of saying the right thing right when I need it – like telling me that I shouldn’t quit the second the thought comes into my mind that I may want to skip the third round (haha!). I also love that each workout is slightly different so it keeps things interesting.
How I Modified 80 Day Obsession Phase 1 With Running
I was training for the Rock n’ Roll Los Angeles half marathon while doing 80 Day Obsession phase 1, so I made modifications to the program. As I explained in my blog post with my 80 Day Obsession & running sample workout calendar, combining 80 Day Obessson with half marathon training is possible, but given the length and intently of the workouts, I do recommend dropping at least one workout per week to give yourself time to recover. Given that I’m only 6 months postpartum from my twin pregnancy, taking care of three children 3 and under and not getting as much sleep as I’d like, I knew I’d have to made modifications.
I generally try to run 3 days a week. The first week of 80 Day Obsession, I thought I could just skip Cardio Flow and do the other 5 workouts along with my 3 runs. However, I was able to do all of the other five 80 Day Obsession workouts but I only managed to get in 2 runs that week. So, the following week and every week since, I have skipped both Cardio Flow and Cardio Core and I just do Booty, Legs, Total Body Core and AAA and I run 3 times (a long run and two shorter runs, ranging 3-5 miles). I try to take one rest day and double up one day, but unfortunately that doesn’t always happen and some weeks I work out every day with no breaks.
80 Day Obsession Nutrition
I admit, I did not follow the nutrition plan. I am a big advocate of following the nutrition plan because I truly believe that it makes a HUGE difference in results, especially if weight loss is your goal. The timed nutrition is very specific and with everything going on in my life, I didn’t get my act together to figure it out. Instead I ate a balanced diet and followed more of an 80/20 rule when it came to healthy foods vs. treats. In the end, it showed in my results but I still feel like I’m getting better results (now that I’m in phase 2 I’ve actually recommitted to my nutrition so more on that in my next update).
80 Day Obsession and Running Phase 1 Results
In Phase 1 of 80 Day Obsession & running, I lost 2 pounds 2 inches (1 off my waist!). Overall, I feel stronger, leaner and better. My legs feel incredibly strong and my running improved. I also feel like my abs/core is stronger!

Girl! You are rocking it! And making me think I should give it a go . It’s just the length that kills me! I don’t know if I want to commit to those long workouts for 80 days. BUT, You are rockin it!
Thank you! You should give it a go! It’s a great workout. I think the 4 days makes it a little more manageable. The length is difficult though, it takes me a lot more planning to get my workouts in and I don’t really do them when the kids are awake anymore like I would with the other ones (plus everyone is more needy and mobile now!).
