Being consistent with Isometrics isn't easy but it can make things interesting, especially if it helps with your other training adventures and keeping injuries at bay. One of the things that I will credit Isometrics with is my journey with Pull-Ups. I'm sure you've seen some of the videos by now and yeah there's still some improvement needed but I'm getting better than I was before. That's the beauty of Isometrics, it helps your weak points and strengthens areas needed or to get more strength in the tendons and ligaments so you can do certain things like Pull-Ups and such.
A good portion of my Isometric Routine is pretty basic by sticking with exercises in 1-3 positions doing 7-12 second contractions at a time. In most workouts, I keep it around 20-30 total contractions, sometimes more, other times less but work into the exercises I'm doing and hammer them out. Exercises are mainly, Bicep Curl, 3 Variations of the Wall Sit, Chest Press, Deadlift, Zercher Squat, Shoulder Raises, Overhead Shoulder Press, Hybrid Push-Up and Core Exercises like Hybrid Plank, Side Bends, Hollow Body Flex, Arch Body Flex, Dead Bug Crunch and Side Planks. I switch some exercises around depending on what I'm feeling that day and do them in a various order to go from one to the other. Some exercises I take a breather on but others, I just hit one and then adjust and keep that going until I feel like I need a breather. Not complicated and doesn't take a lot of time but gets a lot done.
When I go to the gym at times with the wife, I'll test myself on some stuff and slap on the Fat Gripz like Pull-Downs, Farmer's Walks, Bench Press or Rows. I'll throw in bodyweight exercises like Dips doing 5x5 and Pull-ups doing sets up to 3-5 and keep it there or do a countdown method. Suspension Training as well like Rows, Amosov Squats, Curl, Push-Ups or whatever I can come up with. Most of the time, I have no plan at all and just run with whatever pops into my head. Keep the reps at a minimum depending on what I want to do. Never to failure and try to keep gas in the tank. Take rest periods as long as needed, plus it helps to pass the time so when the girlie is ready to head out, it pans itself out.
Because of methods like Isometrics, it has helped maintain my strength and even increased it in some things like being able to pull nearly the whole stack in pulldowns with the Fat Gripz on, Smith Bench up to about 280 with FG's on and so on and so forth. Never feeling sore or even feel like my joints are wearing down at all. They've helped me be in better control when I do movements and harness that mind/muscle connection. At the gym, it feels more like a day off than anything but it's fun and I do get questions from time to time with the FG's but for the most part, I keep to myself, nobody bothers me and every now and then, I'll let someone know they're killing it in their routine. That's really the thing is to cheer each other on and let others know what they're doing is awesome.
I kind of look at Isometrics as not only the Cheat Code to training but also (in a fun way) like the way the Sith's powers in Star Wars. Paraphrasing a quote from Emperor Palpatine in Episode 3: Revenge Of The Sith "Isometrics is a pathway to many abilities some consider to be unnatural." It's very true from a certain point of view (again channeling my Star Wars nerdom) that Isometrics develops strength that still continues to be studied and learning the concept of what it means to be strong and resilient. It formulates power that can turn your weakest links into something that could be considered superhuman or become so strong that you wonder why you didn't learn this in the first place. In my own training, it is giving me abilities at 40 that I didn't think could keep going from my 20s and 30s along with being leaner since losing the weight.
Keep at it guy and make Isometrics a part of your training, it does wonders for your body that will help things in later years and give you levels of strength that will give you a quality of life that seems like an impossible dream but can be very much real.
