The Asuna 8730G treadmill solves a specific problem: you want a real motorized treadmill, but you don’t have a spare room to put it in. AnilKK, an INFS-certified nutrition and fitness coach with 24 years of running experience and 250+ treadmills personally tested, breaks down whether this space-saving model — which folds down to just 5.25 inches flat — is worth it, based on verified specs from Sunny Health & Fitness and over 1,300 current Amazon reviews.
Quick Answer: The Asuna 8730G is a 2.5 HP motorized treadmill built for small spaces — it folds flat to 5.25 inches and slides under a bed or couch. It supports users up to 220 lb and speeds up to 8 MPH, but has no incline and no heart rate monitor. It’s best for walkers and light joggers in apartments or tight rooms, not serious runners who need incline training.

The single biggest reason to consider this treadmill is the fold-flat design — at 5.25 inches folded, it’s slim enough to slide under most beds and couches, which most “foldable” treadmills in this price range can’t match.
What Makes It Different
Most “foldable” treadmills still fold to a bulky, freestanding unit that leans against a wall — this one folds nearly flat. At 5.25 inches high when folded, it’s genuinely low-profile enough to disappear under furniture, not just fold up smaller. That’s the entire design premise, and it’s the one thing that separates it from most other budget folding treadmills we’ve tested.
The tradeoff for that slim profile is a stripped-down feature set: no incline, no heart rate sensors, no preset workout programs. This isn’t a training tool for structured workouts — it’s a straightforward walking and light-jogging machine, and the design reflects that clearly. Anyone considering our under-desk treadmill picks for a similar low-profile need will notice a lot of the same tradeoffs show up there too.
The 220 lb weight capacity is on the lower end for this treadmill category — worth checking against your own weight with some headroom before buying, since a compact frame like this isn’t built for pushing right up against its stated limit.
Best for: Apartment dwellers or anyone in a small space who wants a real motorized treadmill for walking or light jogging, and needs it to disappear under furniture when not in use.
Pros:
- Folds to just 5.25 inches — slides under most beds and couches
- 2.5 HP motor runs quietly with minimal vibration thanks to the built-in flywheel
- Arrives fully assembled — no tools needed beyond unfolding it
- Transport wheels make it easy to move between rooms even at 95 lb
- Over 1,300 Amazon reviews with a strong track record for the price point
Cons:
- No incline of any kind — not suitable if you want incline training
- No heart rate monitor built in; you’ll need a separate wearable to track it
- 220 lb weight capacity is lower than many comparable folding treadmills
Is the Asuna 8730G Right for Your Space? 5 Things to Check First
1. Under-furniture clearance. Measure the gap under your bed or couch before buying — you need at least 5.25 inches of clearance for the treadmill to actually slide under it, plus a little extra for carpet or an uneven floor.
2. Your actual workout style. Because there’s no incline and a top speed of 8 MPH, this suits walking and light jogging, not interval training or serious distance running. If incline work matters to you, look at our best folding treadmills roundup instead, which includes incline-capable options.
3. Your body weight relative to the 220 lb cap. Compact treadmills generally have lower weight limits than full-size models, since the frame is built lighter to keep the fold-flat design possible. Give yourself real headroom below that 220 lb limit rather than buying right at the edge.
4. Whether you need heart rate tracking. There’s no built-in sensor here, so if heart-rate-zone training matters to your routine, budget for a separate chest strap or watch.
5. How you’ll use the tablet holder and speakers. The console includes a tablet holder and built-in speakers with a 3.5mm aux port — useful if you like watching something or listening to music while walking, but it’s not a smart console with app integration, so don’t expect Bluetooth or workout streaming.
Who the Asuna 8730G Is NOT a Good Fit For
If you’re training for a race, want interval or hill workouts, or need to track heart rate zones during your session, this isn’t the right machine — the lack of incline and heart rate monitoring will get in the way fast. Runners who need a longer deck for a full stride should also look elsewhere; the 49-inch running surface suits walking and light jogging strides better than a sprinting gait.
It’s also not the best fit if you’re near the 220 lb weight limit, since you’ll want headroom on a compact frame like this rather than running it near capacity. For a similar low-profile need with a higher weight capacity, it’s worth comparing options in our budget treadmill roundup before deciding.
Walking regularly, even without incline, still delivers real cardiovascular benefit — the CDC recommends at least 150 minutes of moderate-intensity activity like brisk walking per week for adults, which this treadmill handles well within its intended use case.
Keeping It Running: Maintenance Basics
The belt ships pre-lubricated from the factory, but Sunny Health & Fitness includes a bottle of lubricating oil for future use — plan on relubricating every few months depending on how often you use it. Keeping the belt free of dust and debris matters more on a low-profile unit like this since it sits closer to the floor than a standard treadmill. For a full walkthrough of the process, our treadmill cleaning and maintenance guide covers belt lubrication timing in more detail.
If you’re looking for structured ways to use a compact treadmill like this for actual weight-loss progress rather than just casual walking, our treadmill workouts for weight loss guide has interval and incline-free routines that work within this treadmill’s limits.
Frequently Asked Questions
What is the difference between the Asuna 8730 and 8730G?
The only difference is color. The 8730 comes in silver, while the 8730G comes in gold. Both share identical specs, motor, warranty, and pricing on Sunny Health & Fitness’s official site.
What is the warranty on the Asuna 8730G?
The frame carries a 5-year warranty, while parts and components are covered for 180 days. This is verified directly from Sunny Health & Fitness’s official warranty policy.
How much does the Asuna 8730G weigh?
The treadmill weighs 95 lb once fully assembled. Despite the weight, built-in transport wheels make it manageable to move between rooms without help.
Who makes the Asuna 8730G treadmill?
Asuna is a commercial equipment line produced by Sunny Health & Fitness, a fitness equipment company. The 8730G is one of two color variants in this specific space-saving treadmill model.
Does the Asuna 8730G have an incline?
No. This model has no incline feature at all, which is part of what allows it to fold nearly flat for storage. If incline training matters to you, look at a different folding treadmill model.
Can the Asuna 8730G fit under a bed?
Yes, in most cases. Folded, it measures 64 inches long, 30.5 inches wide, and just 5.25 inches tall — low enough to slide under most beds and couches, though it’s worth measuring your specific clearance first.
Is the Asuna 8730G good for running?
It’s better suited to walking and light jogging than serious running. The 49-inch running deck and 8 MPH top speed work fine for a walking stride, but faster runners with a longer stride may find the deck too short.
How much weight can the Asuna 8730G support?
The maximum user weight is 220 lb. This is lower than many comparable folding treadmills, so it’s worth checking your weight against this limit with some headroom before buying.
