The Speediance Gym Monster 1 & 2 are incredible all-in-one home gyms straight out of the box. But like any serious lifting setup, the right accessories can unlock new exercises, improve safety, and make your workouts smoother.
We've tested dozens of third-party and official add-ons. Here are the top 5 essential accessories every Gym Monster owner should consider in 2026.
1. GMVoice Smart Control Module
"The single most important safety upgrade for solo lifters."
Why you need it: Standard Bluetooth rings run out of battery, disconnect, or are hard to press when you're straining under heavy load. GMVoice solves this completely.
It plugs directly into the USB port for zero latency and listens for the "Jarvis, Turn Off" command to release weight instantly. It turns your Speediance into a true smart gym.
- Compatible with Gym Monster 1 & 2
- Hands-free weight release (life-saver for bench press)
- No batteries required
2. Adjustable Bench (Third-Party)
While the stock bench is functional, many users find upgrading to a sturdier, FID (Flat, Incline, Decline) bench improves stability significantly. Look for a bench with a smaller footprint to fit the Speediance platform area.
Recommended: Rep Fitness AB-3000 or Bowflex SelectTech Adjustable Bench. Both offer excellent build quality and won't break the bank.
3. Tricep Rope Extension
The standard handles are great, but a dedicated tricep rope allows for better range of motion on pushdowns and face pulls. It's a cheap accessory that adds huge value to arm days.
Pro tip: Get a rope with rubber end caps to prevent fraying and ensure a comfortable grip during high-rep sets.
4. Ankle Straps
Don't skip leg day. High-quality padded ankle straps allow you to perform glute kickbacks, hip abductions, and hamstring curls using the Gym Monster's cables.
Look for straps with reinforced D-rings and thick neoprene padding. Your ankles will thank you after a heavy glute session.
5. Floor Protection Mat
The Gym Monster is heavy. A high-density rubber mat not only protects your floor but reduces vibration and noise, which is crucial if you live in an apartment.
Size matters: Get a mat that's at least 6x4 feet to cover the entire footprint of the machine plus some extra space for movement.
Conclusion
Physical accessories like benches and ropes are important, but GMVoice Control is the only accessory that fundamentally changes the safety and flow of your workout. It's the difference between fumbling with buttons mid-set and having complete hands-free control.
If you're serious about training safely and efficiently, voice control isn't just nice to have — it's essential.
