If you're into fitness like we are here at ROKFORM, you likely love the fact that your smartphone can fire up your workout in so many ways. It can double as the perfect music player, helping you stay pumped up during a workout,  you can use apps to track your fitness progress, and you can even use it for a gym selfie. Using your smartphone while you work out might sound counterintuitive, but hear us out – there are plenty of other ways to use your phone to step up your workout. 

While your smartphone itself holds many capabilities to boost your workout, the phone case that you use can make a huge difference! From easy access to protecting your phone from accidental drops while moving from machine to machine, the perfect phone case can make all the difference to your gym session. So, what's the best phone case for the gym, and how it be used to maximize your gym performance? Let's find out!

The Best Way to Use Your Smartphone and Phone Case at the Gym

If you bring your phone with you to the gym, you are likely one of two camps – you keep your phone locked up in your gym locker, or you take it with you while you are doing your workout. If you usually keep your phone in your locker, the next time you hit the weights, you might want to consider bringing your phone for the ride.

ROKFORM has a variety of protective cases for iPhone and Samsung smartphones that can not only keep your phone safe but make your workout easier. With a built-in magnet, you can easily attach your phone to any magnetic surface to check your form or use a fitness app – including your kettlebell or water bottle!  

1. How to Improve Your Form at the Gym

Maintaining proper form is critical to completing any exercise safely and effectively. While the wall mirrors that cover the gym walls are extremely helpful, your smartphone can provide additional support. If you’re unsure whether you’ve got the right form or just want the footage to review later on, consider recording your workouts. 

ROKFORM smartphone cases are a great option and are made with super strong (and completely safe) magnets built into each case. This cell phone case makes it easy to mount your phone onto most machine surfaces, switch the camera to selfie mode, and record your workout. You can easily playback your workout and correct your form in real time. 

Our ROKFORM ambassador Breena Martinez, 6x IFBB Pro Champion and 6x Olympian shared how she uses her magnetic case to improve her form, "It is imperative that I have solid form in everything I do to prevent injury and to ensure proper symmetry. I use my magnetic phone case from ROKFORM to critique myself. I record myself when I train and when I am working on my posing routine. It is extremely helpful because many times you may not realize you are doing exercises incorrectly until you record and play it back. If you are looking for a durable, magnetic phone case that won’t damage your phone, look no further!" 

So the next time you want to check your lifting form out, remember that a ROKFORM case is the top choice. All you need to do is mount your phone to any magnetic surface at the gym and start shooting! ROKFORM has iPhone and Samsung cases, with Magsafe options, so you can rest assured that we have the best phone case for the gym that fits your needs.

2. How to Improve Your Timing at the Gym

Timing is everything when it comes to getting the most out of your workout. Whether you are resting between sets, doing a HIIT workout, or timing your long runs, your workout will be more effective if you're mindful of your workout length, and rest between intervals. If you are one to usually leave your phone in your gym locker, take it along with you and time your next workout. You might notice that you start to push yourself even more and get results faster.

With any of ROKFORM's magnetic cases, your smartphone is protected, mounted, and visible during workouts. They are the best iPhone cases and Samsung cases to have on hand during your gym session. Using your smartphone as a countdown timer, stopwatch, or both, will help you time your intervals and rest periods perfectly to achieve your fitness goals.

3. How to Get Workout Inspo at the Gym

If you’re getting tired of your current workout routine, don’t worry. Get some much-needed workout inspiration by using your phone as a visual aid to guide you through new workouts. A ROKFORM-mounted smartphone is a great case to use for this. With a ROKFORM magnetic iPhone or Galaxy S case, it’s easy to try some new exercises out at the gym. Pre-save key exercises prior to your workout so they are easy to access during your workout. Simply pull up your favorite fitness app or video, stick your phone on a magnetic piece of equipment, and get to it!

4. How to Use Fitness Apps at the Gym

There are thousands of fitness apps available for download. Some focus on providing comprehensive exercise routines depending on your fitness goals, while others give you just the nudge you need to get off the couch.

Perhaps it’s the idea of adding competition to win daily step challenges against friends, the feeling of joining a new community through app discussion boards, or maybe just the visualization of your fitness progress that keeps you going back to the app (and the gym). Regardless of what it is, it’s working! In fact, a recent study on fitness apps found that people with fitness apps were more active than non-users.

5. How to Keep Your Workout Hands-Free

After all the great tips we just mentioned, there’s one thing you definitely don’t want your phone to do while working out – get in your way!

CrossFit Forest saw a client using his ROKFORM case to stay hands-free at the gym and loved it so much, they bought ROKFORM cases to protect all of the tablets at the gym. Pete Jones, owner and trainer at the CrossFit gym in Lake Forest, California, found the ROKFORM cases immediately solve a gym-wide issue: “We needed a way to protect [the iPads] and be able to station them throughout the gym without them being on the ground or susceptible to having a weight dropped on them. We attach [iPads] all over the place and feel like we’re able to keep them safe and protected from the ground, from having weight dropped on them.” There's no doubt that they believe that ROKFORM offers the best protection in a gym environment!

Frequently Asked Questions

Am I Using the Proper Form at the Gym?

There are several aspects to think about when it comes to proper form at the gym, including spinal alignment, joint alignment, range of motion, and tension. Proper form is essential for success when training for anything from general fitness to sports events and/or competitions. It is the quality of training that influences your progress, more than the quantity. Time under tension, angle of movement, range of motion, and many other factors all contribute to a particular resistance training session. It is important to understand the proper mechanics of training to get the most benefit from your time.

How Long Should I Rest Between Exercises?

The answer to this depends on the individual. Everyone has their own strength and body goals, and knowing those goals is critical to setting an appropriate rest period. According to ISSA, the International Sports Sciences Association, it takes between two and three minutes for the phosphagen stores to fully recover from a set of intense exercises. For athletes whose goals are related to absolute strength, the optimal rest period between sets is 3 to 5 minutes. For endurance athletes, the optimal rest period between sets is 30 to 60 seconds.

In addition, the more that you train, you may notice that you need less recovery time between sets. Using the best magnetic phone cases from ROKFORM, you can easily track your time and notice the improvement that you make as your training and endurance improves.

What Are the Best Fitness Apps?

We haven’t been able to try them all, but we did find some of the most highly recommended apps. Some of our favorites include Couch to 5K, Nike+ Training Club, Sworkit, Lift Log, and CycleCast. If you’re old school and prefer browsing some high-quality workout articles, check out the comprehensive workouts provided on Since the beginning of the pandemic, thousands of gyms and fitness trainers have shifted workout programs online, and though fitness centers have since reopened, many have chosen to keep their online platforms active.

Will the magnet in your phone cases hurt my phone?

NO. Manufacturers have been using magnets in phones and tablets for years. Our specially designed rare earth magnets are proven safe for all smartphones and tablets. In a product overview from MacWorld, they said: "magnet based accessories are safe to use on iPads and pose no threat of scrambling interior electronics.” Our magnets will not harm your credit cards either. Magnets will only affect spinning hard drives found in old laptop and desktop computers. The magnet also may affect a hotel key but then again what doesn't? Bottom line, our magnets are safe but don’t set your phone on your old computer or your hotel key ;-)
