Question: Approximately how long does it take to change from one exercise to another? Does it take long to attach and detach the pulley system?
Document: Chest presses do not equal bench press, so the 4 pulley set-up is simply wonderful. Accessories take just seconds to change, pulley system from 3 point to 4 point can be done in about 1 min.Weight accessories- you of course have to add weights if needed to add resistance. I like this option, but there are issues. First off grabbing the handles or bars with weights attached can be a real challenge. At high incline levels it is extremely hard.
This gym pack surpassed my expectations. I am 6'1' and just a pound or two lighter that 300 pounds. This machine supports me just fine and the change in resistance levels is fast and easy, so I can work out with my daughters or my wife. The 4 system pulley really adds resistance and it is very strenuous to work the bench press on a 4 system. With the included weight bar, I can see this machine working well with the most fit individual to the least fit.
I had to email and call customer service the first month because the stitching in the ankle cuffs was ripping. Customer service by phone was excellent, they sent me a whole new pulley with the ankle straps attached within a matter of days. Customer service email to their web site was another story, I still haven't had a response through there. Use the phone. Total gym sells ankle straps that attach to the foot and ankle simultaneously. I'm currently looking into buying a pair of those.
The design with the powerbar to add weights gives me the ability to add more resistance then I need to wear myself out.Moving from one lift to another can often be done without having to change anything, but even if you need to make an adjustment for another motion/body part it is quick and easy. Very much like circuit training in a gym full of equipment.The machine itself is VERY well built, very solid.
I haven't exercised regularly in quite a while and was somewhat concerned about buying this exercise equipment. But I have to admit it's one of the best buys I've made this year. Very easy to attach accessories, you can complete movements very easily without constantly having to get on and get off. I can easily tell that my muscles are getting a great workout.
I followed the "beginners program" (3 sets of 12 reps each) to ease my way back into working out and I am sore. Not a bad sore but a good sore. I did not notice any bumps but it did take a little getting used to. I read one of the reviews, somewhere, that said it was boring after a month! DUH, look up the definition of exercise. Don't blame this machine.
I am really enjoying using my trainer. I use it daily. It is so versatile and easy to set up and adapt for each exercise. It did take me some initial prep time to understand the exercises and configurations required, but Im proficient now. It came with 2 dvds and one of them doesn't work and the instructions leave a bit to be desired, otherwise I would have given it 5 stars. A great investment over all.
I was looking for an exercise station that wouldn't take up much space in my crowded, low ceilinged basement and after about a month of use I'm satisfied I found it in the Bayou Total Trainer. I also like the wide range of resistance-based exercises, the ease of assembly (and I say that as someone not considered &#34;handy&#34;), and the price.
Also, the superior build quality was apparent, with a more robust glide board and a lifetime warranty on the pulleys, cable, and  rollers. We also noticed how much smoother the roller action is on the glide rails. You also get more attachments than come with an equivalently priced Total Gym. Another big plus is the ability to add additional free weights to the DLX III (for more resistance) using the included weight bar. I do have one piece of advice for anyone who buys the Total Trainer DLX III.
I'm not a big guy but I do have broad shoulders and wish the bar was a few inches longer.Sit up strap - a complete waste. Just do incline sit-ups or crunches. If your back is weak, you can use the leg pulley rope to assist. The leg pulley attaches on the upper part of the post and has a loop on one end that attaches to the glide board.
Answer: yes
