Question: Can I do leg press using these bands?
Document: These would be of concern when using bands for standing, foot/floor anchored, overhead triceps extension/shoulder press. These would be good exercises combined with squats. I went to quite a few sites and found no such info. These would be safety issues.
In order to do a shoulder press, I found I needed to sit on a chair to do the exercise. So if you can deal with that inconvenience, these are a nice cheap alternative to getting the P90x bands.FYI, I am 5'9." Perhaps if you are 5'2" or less this may not be an issue.So if the bands were longer I would give them 5 stars.
However these bands are so long that doing some exercises, even as demonstrated in the booklet, is impossible. For instance to do a &#34;bench press&#34; they demonstrate the bands going behind the shoulders while laying on the floor then extending your arms up perpendicular to the floor; like a bench press.
I am using these bands in conjuction with the P90X workout and they are perfect! The only setback is that I am a little concerned sometimes about the way it connects to the door.
I was pleased with this product. Been using it now for a couple months and I found it to be much sturdier than the Walmart junk I had before. If I could think of anything wrong it would be that the bands are not quite long enough.
I have started using the bands with my P90X workout and they are pretty good. I was afraid they were going to pop but they are standing to up to what i am throwing at them. I just wish they would come with some more instructions on how best to store them, other motions etc.
I have had a few varying tension latex resistance bands that have all previously broken on me during working out. I warn anyone using a latex resistance band, regardless of ANY strength, it will eventually wear and tear and SNAP on you, pretty much guaranteed to be while working out.
As far as the strength of the cords, this item is great. Though I'm not very strong, and am using this for light exercising with my Wii eaActive game, so maybe my opinion isn't the best to listen to if you're purchasing this with ideas of heavy heavy strength training.I like the quick clips for changing the bands.
I cautiously tested this anchor, and ended up deciding that I would not trust it. So I ended up using a ratchet strap I had laying around as my door anchor and it's been working great.If you're looking for a great set of bands, with high resistance for back exercises, look no further. However, be careful with the door anchor!
I purchased these bands to start the P90x workout program. I was looking forward to get the program going and get in shape. After using these bands 1 time, yes 1 time, I had a band snap and hit me in the arm! I am not a very strong guy by any means, and this band broke like a cheap rubber band!!
Answer: yes
