So far, I'm really excited and impressed by this new program of Jessica's.

I've done five Lift and Shift workouts so far, and I feel like they're absolutely the perfect kind of challenge for where I'm at right now. I love that they're challenging without being frantic or stressful. It's really nice that they don't take up much space, and I don't have to get out tons of equipment. I really like how calm and motivating Jessica is, and the various motivational quotes and uplifting comments are just what I need right now. (Pandemic fatigue has set in hard!)
Just for a little background, I've been doing Cathe's workouts for the last year or so. I started with LITE and ICE, then moved on to Xtrain in the summer. I hurt my back in the fall and after a few months of rehab, I got back to doing Cathe's weight work in January and February (Perfect 30, Strong & Sweaty and some of her older stuff). I went through all of Jessica's Walk Strong sets back in 2018-9, so I knew that I liked her stuff, but I was a little worried that I'd "outgrown her" since I've been doing Cathe. But Lift and Shift definitely isn't too easy for me. She has you do deeper, slower squats, and her leg presses are slower and with a greater range of motion too. And she has you do one-legged pistol squats, which I totally can't do with much weight at all yet. She also has more functional movements--like the stuff where you practice getting up and down off the floor without using your arms. I kind of knew that I needed to work on such things, but it was easier just to keep doing what Cathe tells me to do.

Jessica also includes core work in just about every workout, and with Cathe you often have to tack on core after you've already done a 45-50 min workout. So for me, that meant I only worked my core about twice a week.
So anyway, I think this program is going to work well for me. The one reservation I have is whether I can keep doing these same workouts for three months. The 90-day Xtrain rotation really got to be a slog at the end. But I'm willing to give it a try. At least I get to throw in whatever cardio workouts appeal to me each week. Maybe that'll be enough variety, for a variety-junky like me!
