Question: How does P57 compare to other barre programs, such as Ballet Physique? Does anyone with experience with both recommend one over the other?
Document: I love doing Barre!! The exercises are challenging yet fun. I just love the instructor I actually laugh while I'm doing the workouts. She's very motivating and upbeat and I'm always sweaty and happy when I get done with a workout. My one and only complaint would be the quality of the ball it comes with.
As a former ballet dancer, this exercise program blew me away. It reminded me very much of my old barre exercises, but on &#34;steroids&#34;. I've been doing the exercises exactly as recommended, and I've already lost 2 inches off my thighs, in 2 weeks. I was doing hot yoga, and the elliptical machine before.... I'm so glad I found this DVD set.
I did one of the 30 minute tapes and my abs were killing me the next 2 days! Its amazing! I love switching them out with my Pop Physique DVDs although the Pop Physique DVDs are a lot harder to do but both of them are totally worth it!
I've taken a couple of barre classes in person (not Physique 57), but struggled to find times at local gyms that worked with my schedule ... and my budget. This set of DVDs is the perfect solution! I'm able to mix up my normal gym routine (mostly Spinning and Body Pump) with Physique 57. The 30 minute DVDs are great when I'm limited on time, but still want to squeeze in a quality exercise session.
I love, love, love these workouts. After years of pounding my body with high impact cardio and heavy weight training, I was looking for something that was just as challenging, yet gentler on my joints. Enter the Physique 57 workout collection. After doing these workouts, I consider them to be the gold standard of barre workouts. I have added many other barre workouts to my collection, but I always come back to Physique 57.Why I love these workouts:* They work!
Physique 57 is one of the most intense workouts I've done, and I love it. I've done BodyCombat, Chalene extreme, Zumba, Brazil butt lift, jogging, strength training, yoga, you name it. Physique 57 looks pretty simple and easy, but it really gives you a great workout and is a lot of fun at the same time. I usually alternate it with my other workouts so that I don't get bored doing the same thing every day.
If you have knee problems, I would not recommend this set.
Great workout! These DVDs are now a staple in my workout routine. They are challenging but the time goes by fast. Cannot recommend them enough!
Only wish I could participate in a live class but this is the next best thing, may want to trade out ball that came with it for heavier duty one.
I am truly addicted to the workouts. I use these videos in addition to cycling and another ballet/pilates class at my gym and I feel a lot better than when I was lifting &#34;heavy&#34; weights all the time.I don't have anything negative to say...just more videos is my only request!
