Isometric exercises are contractions of a particular muscle or group of muscles. During isometric exercises, the muscle doesn’t noticeably change length and the affected joint doesn’t move. Isometric exercises help maintain strength. They can also build strength, but not effectively.
Because isometric exercises are done in one position without movement, they’ll improve strength in only one particular position. You’d have to do various isometric exercises through your limb’s whole range of motion to improve muscle strength across the range. In addition, since isometric exercises are done in a static position, they won’t help improve speed or athletic performance. They can be useful, however, in enhancing stabilization — maintaining the position of the affected area — since muscles often contract isometrically to aid in stabilization.

While Isometric Exercises may consist of engaging muscles in a stationary position. Dynamic Exercises – refer to the movement of a muscle group in a specific direction or action. Think, bench press, dumbbell curls etc. The fundamental purpose of this style of workout – is to move a set amount of weight, whether small or large.
Why Not Combine Both?
This work compares the specific effects of 3 mo of moderate, isometric, or dynamic voluntary exercises on the contractile properties of human adductor pollicis muscle. Isometric training consisted of 10 daily contractions of 5-s duration at the frequency of one contraction per minute. Dynamic training consisted of 10 daily series of 10 fast contractions (less than 0.5-s duration) moving a load of one-third of the maximal muscle strength at a frequency of one series per minute. Both training programs produced a concomitant increase in maximal tetanic tension and in peak rate of tension development (Ro). A larger increase (P less than 0.05) was found after isometric training (20 vs. 11% after dynamic exercises), whereas Ro augmented more (P less than 0.05) after dynamic contractions (31 vs. 18% after isometric training). Enhancements of twitch force (Pt), rates of twitch tension development (Rt), and of relaxation (St) were, respectively, 20, 20, and 12% after isometric training. There was no modification of contraction time and time of half relaxation (T 1/2R). Conversely, dynamic training produced increases of Rt (25%) and St (16%), associated with an apparently paradoxical decrease of Pt (10%) and reductions of contraction time (11%) and T 1/2R (9%). Maximal shortening velocity was only increased after dynamic training (21%), whereas the maximal muscle power presented a large increase (P less than 0.05) after isometric exercises (51 vs. 19% after dynamic exercises) and a shift of its optimal peak toward heavier loads. This study suggests that human muscle adapts differently to isometric or to dynamic training programs and provides evidence that its contractile kinetics can be altered by exercises performed in physiological conditions.
From Then, To Now
Co-founder Ryan Baldwin had just moved to Austin, TX for a new start with his wife. A true believer in ‘things happen for a reason’ and ‘we’ll figure it out’ he picked up a job in retail sales to allow him and his wife the flexibility for her to follow her passion, and him to easily transfer jobs anywhere. That anywhere took him to Austin, TX.
Co-founder James Parker had just moved to Austin, TX with his wife (then girlfriend) to follow her passion of working in the music industry. She had a unique opportunity come up and I told her – this is too good of an opportunity to pass up. So, I quit my job I had at the time for a graphic design firm and found a retail store that would allow me to transfer anywhere.
September 2015 Ryan and James just so happen to transfer to the exact same store, within just a few days of each other. The first day they worked together they knew there was something there. Spending close to 1.5 hours after the store had closed just brainstorming ideas, feeding off each other.
There it was
A number of ideas had come and gone – launched, failed, and successful apps, products, and ventures later they knew it would only take one thing to make it happen.
James had been working out almost daily for 5 years, and had got to a plateau in his fitness and wanted to change it up. So, one day warming up he started to play around with weights and cables in his gym. It hit him there – he felt there was something there. So, the first person he called was Ryan – and of course, he was all in on it.
2 years and close to a dozen prototypes later – the FitDisc was born.
Big Results - Small Spaces
More Important Now Than Ever
With the FitDisc concept holding strong – we make sure to keep our mantra of
We keep that as a primary focus in our everyday evolution of the business.
The FitDisc is the first of it’s kind and at first glance seems very unassuming.
It’s a simple concept – that packs a punch. We found that the disc itself, requiring you to contract the palms of your hands inward doesn’t allow you to lift a lot of weight. Most users will feel results with 20-30 pounds, when normally 50-60 pounds would be required. Why is that?
Simple – you aren’t holding onto anything. You are engaging small fibers in your muscles making sure to keep the disc between your palms. What we have found is that it’s perfect for anyone looking to change up their workout at the gym – by simply attaching it to a cable machine.
Alternatively, and more powerful – we found it extremely useful and very practical with the at home fitness community. Just simply by including 1-2 resistance bands, you can get an entire body workout from something the size of a dinner plate. Ideal for anyone new to working out, needing a change to their workout, looking to add variation to their workout, someone who travels (yes, it is carry on approved). Resistance bands work perfectly for the disc – give it a shot.
