It’s a familiar scenario for many fitness enthusiasts: you’re trying to push your limits, whether it’s through High-Intensity Interval Training (HIIT), Tabata, or simply managing rest periods between sets. I remember grappling with the frustration of constantly glancing at a wall clock or fumbling with a phone timer, breaking my focus and rhythm. This inconsistency wasn’t just annoying; it directly impacted the effectiveness of my workouts, making it difficult to track progress or maintain proper intensity. Having a dedicated, reliable tool like the Gymboss Charge Interval Timer and Stopwatch would have been incredibly helpful in overcoming those early challenges.
Before diving into the specifics of any single device, it’s crucial to understand what makes an interval timer a valuable addition to your fitness arsenal and what considerations should guide your purchase. An interval timer primarily solves the problem of precise timing during structured workouts, allowing you to focus on your form and effort rather than constantly monitoring a clock. This precision is vital for maximizing the effectiveness of training methods like HIIT, Tabata, circuit training, or even specialized drills in sports where strict time limits apply, such as umpire duties in softball. Without accurate timing, these workouts can lose their intended intensity and structure, leading to suboptimal results or even injuries.
The ideal customer for an interval timer is anyone who engages in structured, timed physical activity. This includes athletes, personal trainers, gym-goers, runners, martial artists, yoga practitioners, and even those managing specific tasks that require timed intervals. If your routine involves alternating periods of work and rest, or if you need to adhere to specific timeframes for exercises, then an interval timer is a must-have.
However, an interval timer might not be for everyone. If your exercise routine is highly unstructured, spontaneous, or primarily consists of steady-state cardio without specific time-based intervals, a basic stopwatch or a phone timer might suffice. Furthermore, those who need extremely complex, multi-layered interval programming with more than two alternating intervals might find simpler models limiting. In such cases, a more advanced smartwatch with dedicated fitness apps or a specialized fitness computer might be a better fit.
Before making a purchase, consider the following:
* Durability and Water Resistance: Will it withstand sweat, rain, or accidental drops?
* Battery Life and Charging: Is it rechargeable, and how long does it last?
* Display and Notifications: Is the screen clear, and does it offer audible and/or vibrating alerts?
* Ease of Use: Can you program it quickly and intuitively?
* Portability and Mounting: Is it compact, and does it have a clip or other attachment options?
* Interval Settings: Does it support the number of intervals and repeats your training requires?

Presenting the Gymboss Charge Interval Timer
The Gymboss Charge Interval Timer and Stopwatch is a compact, purpose-built device designed to streamline your timed workouts. Its core promise is to simplify interval training by providing reliable, precise timing without the distractions of a smartphone. When you purchase this handy tool, you receive the timer itself, a secure and removable belt clip, and a charging cable. This particular model, the Charge, represents an evolution from earlier Gymboss timers, notably featuring a rechargeable battery and a backlit LCD, enhancing its practicality and longevity compared to its predecessors which often relied on disposable batteries. While not a multi-interval powerhouse like some more complex fitness trackers, it excels in its niche as a dedicated, user-friendly interval timer.
This specific Gymboss device is ideally suited for individuals who primarily use one or two-interval training protocols – think work-rest cycles, run/walk programs, or dedicated warm-up/cool-down periods. It’s perfect for those who value simplicity, durability, and a hands-free experience during their workouts. It might not be the best choice for someone needing to program three or more distinct interval lengths or highly intricate, custom workout sequences, as its design focuses on efficient management of up to two intervals with multiple repeats.

Features & Benefits
Having used the Gymboss Charge Interval Timer extensively, I can genuinely appreciate the thought that went into its design and functionality. Each feature contributes significantly to a smoother, more focused workout experience.
Compact Design and Portability
One of the first things you notice about the Gymboss Charge is its incredibly compact size. Measuring just 0.55″D x 2.25″W x 1.75″H and weighing a mere 2 ounces, it truly is the size of a small pager. This small footprint is a massive benefit. When I’m working out, the last thing I want is a bulky device getting in the way or bouncing around. The Gymboss disappears on my waistband or pocket, allowing me to move freely without feeling encumbered. Its light weight also means it doesn’t add any noticeable drag, even during high-impact activities like running or jumping. This portability is crucial because it removes a common barrier to consistent interval training – the hassle of setting up or carrying larger, more fragile electronics. It means I can take my structured workouts anywhere, from the gym to the park, without a second thought.
Interval Timing Versatility
Despite its small size, the Gymboss Charge offers impressive versatility in its interval timing. It can time one or two intervals, ranging from as short as two seconds to as long as 99 minutes. This flexibility covers the vast majority of interval training needs. For my own workouts, whether it’s 30 seconds of intense effort followed by 10 seconds of rest (Tabata) or longer work periods in circuit training, the Charge handles it effortlessly. The “Auto mode” is particularly useful, allowing the timer to repeat through intervals up to 99 times. This means I can set it once for an entire workout session and just focus on my performance, rather than constantly resetting or monitoring. The ability to save up to 12 different settings is also a game-changer; I have various routines programmed, making switching between different workout styles incredibly quick and convenient, remembering the setup from previous use.
Stopwatch and Clock Functionality
Beyond its primary interval timing capabilities, the Gymboss Charge also includes a built-in stopwatch and clock feature. While seemingly basic, these additions add significant value. The stopwatch is perfect for timing ad-hoc exercises, tracking recovery periods, or even just timing a sprint. Having the current time displayed is also a subtle but appreciated feature, meaning I don’t need to pull out my phone just to check the hour. These supplementary functions make the Gymboss a more comprehensive time-management tool for general daily use, not just for dedicated workouts.
Secure and Removable Belt-clip
The included secure and removable belt-clip is an unsung hero of this device. A timer is only useful if it stays with you, and the Gymboss’s clip is robust and reliable. I’ve clipped it to my shorts, waistbands, and even sports bras, and it has never once come loose during strenuous activity. The “removable” aspect is also key, allowing you to attach it to the optional watch strap (fitting all Gymboss Accessories) if you prefer wearing it on your wrist. This secure attachment ensures that the timer is always within reach and that I can reliably feel the vibration notifications, which is crucial for staying on track without constantly looking at the display. One user mentioned the importance of the clip, and indeed, it makes the device practical and truly hands-free.
Customizable Notifications
Effective notifications are paramount for an interval timer, and the Gymboss Charge Interval Timer and Stopwatch excels here with both chime and vibration options. What truly sets it apart is the ability to set the alarm duration for one, two, five, or nine seconds. This level of customization is invaluable. During intense exercise, I might not hear a soft chime, so the vibration is my go-to. Being able to set it for a 2-second vibration, as one umpire noted, ensures I don’t miss the alert, even in noisy outdoor environments or when my focus is completely elsewhere. For quieter settings, or when I don’t want to disturb others, the chime is perfect. This dual notification system, combined with adjustable duration, makes the Gymboss highly adaptable to any training environment and personal preference, making the product incredibly effective at signaling transitions.
Backlit LCD Display
Visibility is often an overlooked feature, but the Gymboss Charge addresses this with its backlit LCD. Whether I’m working out in a dimly lit gym, an early morning park before sunrise, or under direct sunlight, the display remains clear and easy to read. This is a significant improvement over timers without backlights, where trying to decipher the time in poor lighting can be a frustrating and workout-disrupting experience. The backlight ensures that I can quickly check my progress or remaining time at a glance, maintaining my focus on the exercise itself.
Weatherproof Construction
The product description claims the Gymboss Charge is “weatherproof, allowing for use in heavy continuous rain as well as extreme sweat and humid conditions,” explicitly stating it “cannot be submerged in water.” This is a crucial feature for anyone who trains outdoors. I’ve certainly put it through its paces in various conditions – sweaty runs, humid yoga sessions, and even light drizzles. For the most part, it holds up well, and it’s comforting to know that a little moisture won’t instantly ruin it. However, it’s important to address user feedback here. Some users have reported issues with screen fogging and temporary malfunctions after exposure to heavy sweat or continuous rain, suggesting that “weatherproof” might not equate to full water *resistance* in all practical scenarios. While the company seems to offer replacements for these issues, it’s a point to be mindful of; safeguarding against *excessive* moisture, especially prolonged heavy rain or extreme sweat, might still be a good idea despite the claims. It’s a robust device for general use, but perhaps not entirely impervious to all forms of moisture ingress under extreme conditions.
Rechargeable Battery Life
One of the standout improvements of the Charge model is its built-in rechargeable battery. The product claims it will last for months on a single charge, and in my experience, this holds true. It’s incredibly liberating not to worry about constantly replacing watch batteries. The included charging cable makes topping it up simple. This long battery life is a testament to its efficiency and convenience, ensuring that the timer is always ready when you are. A small point of contention from user reviews, however, is the charging port: while some modern devices use USB-C, the Gymboss Charge appears to use a Micro-USB connector, which might be an inconvenience for users with primarily USB-C cables, though it doesn’t detract from the excellent battery performance itself.
Social Proof (User Review)
Having scoured the internet for other users’ experiences, it’s clear that the Gymboss Charge Interval Timer resonates positively with many. Users frequently praise its intuitive setup and the memory function that retains previous settings, making it hassle-free for recurring workouts. The customizable vibration feature is a consistent highlight, especially for those in noisy environments like outdoor sports or crowded gyms, ensuring they don’t miss their interval cues. While some feedback pointed out a potential vulnerability to extreme moisture despite its “weatherproof” label, and confusion regarding the Micro-USB port, the overwhelming sentiment celebrates its durability, long-lasting rechargeable battery, and overall effectiveness as a reliable training companion.
Conclusion
In the realm of structured exercise, the challenge of maintaining precise timing and focus is persistent. Without a dedicated tool, workouts can easily become inconsistent, leading to plateaued progress or even frustration. The Gymboss Charge Interval Timer and Stopwatch offers a straightforward yet highly effective solution to this problem. Its compact size and robust build make it an unobtrusive addition to any workout, while its versatile interval settings and customizable notifications empower you to stay on track. This reliable timer is a great fit for solving your timing woes because of its long-lasting rechargeable battery, clear backlit display, and secure belt clip, all contributing to a seamless training experience.
