The TNT Cables from Lifeline Fitness have been one of my favorite tools of resistance band training for years. Off and on, I kept the exercises simple and basic. Hell of a traveling apparatus as well since you can fit the handles and the cables inside your duffle bag. With the door attachment, there are many exercises you can do just like you may do in a gym. Very versatile and a great idea for training.
Every once in a while, I'd like to spice things with them and attach my Fat Gripz to the handles to simulate Thick Bar Training. Usually just keep to about 4 Exercises (Curls, Pulldowns, Rows & Chest Presses) and do one arm or two arm versions of those exercises. For a period, I would have a set number of reps and work with that and use heavy resistance (around 100-200+ lbs of resistance) depending on the exercise I do. Lately, I've gotten back into that kind of training; the exercises stay the same but the set/rep scheme has changed. I would do just one set of the exercises but do enough reps where it's a challenge but I'm not going to failure. I try to keep it around enough reps where I have at best 2-3 left in me but make that enough to stop.
This has been a very good workout to work my grip strength and achieve greater muscle activation in the exercises. With this type of training, it's important to not focus so much on speed or resting very little which in most of my workouts is a focus. This is meant to focus more on technique, hitting the muscles hard and resting as long as needed for the next exercise. It's purely more about strength than anything else. For the rest period, I'd say give it 1-5 min depending on how the set goes but that's just an idea, take as much time as you need to feel ready, have the mindset that when you go into the next exercise, you go with a vengeance. Don't hurt yourself and sure as hell don't try to break records or anything, it's not ego lifting.
You can use the Fat Gripz on your dumbbells, barbells and machines to enhance your exercise. Don't try to do so many exercises for so many sets and reps, focus your attention to simplistic exercises as best as possible and keep the amount of exercises short. The old timers knew this very well and had great success because of methods like this. If you're really ambitious, work up to the Fat Gripz Extreme which is close to 3 inches in circumference, this will test you big time. I've only done the Extreme a handful of times ever but I made it count and they're to be respected. Build strong hands for a strong body.
Thick Bar or Handle Training is no joke and you won't do as many reps as you normally would, it cuts the reps to about from what I understand to 1/3rd of what you would normally do so if you could say Bench 315 for 10 reps with an olympic bar, with these Gripz (especially the extreme) the reps would be no more than maybe 3, 4 max so that should tell you how tough these bastards are. I like them because I don't have to spend a ton of time training and don't do as many reps because I want to dig into the muscles hard and get stronger. How often would you work with the Gripz? With consistency, probably no more than twice a week, if you're an advanced trainee that is geared toward pro ranks, maybe 3-4 times a week but that's pushing it. For beginners, if you decide to go that route, start with once a week or every 10 days because these are crazy to work with.
Train with intent, listen to your body and make every workout count to take those steps towards your goals. Be amazingly awesome everyone.
