Question: Can I play these in my Bluray player?
Document: There was a scratch on the surface of the disk.However, there was no problem to play.I did not make an exchange request.
I will say, It's not for the faint of heart. Makes P90x look like childs play. A couple of the workouts can double as torture techniques. Overall, it is helping me get in better shape though.
I purchased this program on Amazon.com after seeing an infomercial about &#34;another&#34; workout. When I checked the price of the &#34;other&#34; workout, I was a little disheartened, so I searched for a more reasonable alternative, which brought me to Rushfit. When I received the DVD set, I found that 3 of the DVDs would not play correctly.
I received this about a month ago. Haven't made it thru the whole program but I like the amount if core exercises. I don't feel the need all the time to bulk the way p90 can sometimes. My only issue is the warm up and cool down are the exact same every time so it gets a little repetitive but I'm getting results so I'm going to keep pushing play
These workouts are great, especially for the core. I play rec hockey and after two weeks of RushFit I already can notice a difference in my slap shot, balance, strength, etcPros:- Great workouts, especially for the core.- Only 25 minutes per workout and they go REAL fast. (I skip the warm up and cool down due to lack of time... oops!
I've been working out for years in the gym, then I tried P90x which wasn't bad but I saw an ad for Rushfit so I thought I'd give it a shot. And man am I glad I did. I'm down 15 pounds and I've never felt better! The best part is that I play hockey as well and with the emphasis on functional training I see a huge improvement in my hockey game!
There are such a large variety of exercises and movements on the DVDs that I have put together a very interesting series of exercises that may end up being 3 times a week in a few weeks ( allow me to watch Northern Exposure/Arrested Development on the DVD player while sweating away) . So why a 5?
I am about 4 weeks into this and loving it. I didn't do the "before" pictures and certainly will not be entereing any contest...just not my thing...I am 52 and have been working on being healthier for the last couple years...We set up a tv and dvd player in the basement, we bought a few dumbells and we are ready to go...Follow the appropriate schedule for your level and work your butt off.
I recommend it to anyone.
I highly recommend it!
