Day 1 for me was great. The workout kicked my butt. I am glad I saw it through. My nutrition has been great today as well.

I ran into a problem today because, for some reason, the Lower Fix workout won't play on any of our devices. We tried it on three different ones. I have a replacement copy coming but, in the meantime, I had to come up with something else. The insert says to replace a 30 minute workout with the 10 minute ab workout if you're pressed for time. So I can do that on top of the lower body workout I did in lieu of using 21DF. The Pilates Fix seems to be playing just fine (I have it going in the background) so I'll be back on track bright and early tomorrow morning.

@KellyBgetsfit I'm just glad that beachbody didn't hesitate to offer me a replacement. It's slowing me down a bit but not stopping me altogether. The ab workout is pretty intense. If your abs are sore, you'll definitely feel it. Maybe on the day you double up, skip the second 30 minute workout and try the abs. After all, she says you can replace a day with just the abs so you'd still be doubling up and it is an option on at least one of the days to double up. I don't want to scare you off or anything but the ab workout isn't easy. It's harder than most I've tried.

jextry, I'm only on day 7 but, like you, I'm planning ahead. I am going to take a week off the 21DF after I've gone through it one time. During that week, I'll be doing other forms of exercise and enjoying my birthday. Then, I'll jump back into 21DF full throttle. Definitely enjoying the program even though sometimes it is tough.

Finally experiencing success! Before I injured my knee last summer, I was doing yoga, using DVDs, sometimes walking, sometimes using a stationary bike. When I injured my knee, everything came to a grinding halt. I was eventually allowed to use the stationary bike but only for 30 minutes and it had to be at the easiest setting, with gradual (only once a month!) increases. But I was finally given the okay to do more exercise and 21 Day Fix was my choice because of the modifications.

Needless to say, I wasn't expecting a miracle and yet here I am over 3 lbs lost after only 2 weeks! Very happy. Next week I'll be doing my "after" measurements. And today is not my official weigh-in day but when I saw the numbers on the scale this morning, I had to share.

@moominpoo‌ I'll be starting it over again on the 6th. If you think you'll be ready by then, I'll be happy to cheer you on. I've been blogging about my first time through here on MFP, linking to my online blog. (I'd just blog here but for some reason MFP flips my pictures sideways and I got tired of having to fix each and every blog post so just dumping a link was easier.)

You can find my blog here.

@Krafty131‌ I love 3 lbs in the first two weeks. And I'm only doing the modified version so, if you can go high impact, you'll probably see even better results. I'm thrilled though. Lovely the program and that I'm able to keep up in spite of my physical limitations.

I don't know if Autumn Calabrese came up with the idea of the portion "tupperwear" but I think that was very ingenious. While I have trained hard for decades, doing myfitnesspal finally got me into managing my consumption... I think her exercise routines my be slightly lighter for me but am tempted to order it just for the tupperwear... :-)

I am on day 7 of the 21 day fix extreme, the workouts are INTENSE but I love it.

@poliro22‌ I am halfway through my third and final week but I plan on doing 21DF again starting 6 April. We may not be synced up as far as the start/stop times but I'm happy to cheer you on.

I will complete my first round tomorrow! I am starting again. However, has anyone found that they plateau? I am doing extreme and the workouts are very hard.. but I am afraid that they are too short and my body will get used to them.

Finished yesterday and took my measurements today. I blogged about my 21 day journey and today I posted my results. http://satia.blogspot.com/2015/03/21-day-fix-results.html

@moominpoo Glad you worked out the DVD issues. My set I had a problem with one of the workouts. The company replaced it and, so I wouldn't lose too much momentum, on the day I was supposed to do the one workout (lower body fix), I went ahead and used a lower body workout in my DVD collection. Wasn't quite the same but I made sure I did 30 minutes and I did the abs workout that day as well.

@rainey4 I started my second round yesterday. I was very impressed with my results the first time around and hope to see similar results. I don't expect to see the same results but if I come close that would be great!

Well had my followup regarding my orthopedic inserts. I have the okay to do DVD workouts, but for the next 2 weeks i have to have a 2 day break between workouts to let my feet rest. I can go for walks in between but thats it.
