TRX Suspension Trainer Review – The Cheapest Way to Keep Your Muscle

A TRX is two straps and a door anchor, from about $135 once, with nothing to subscribe to. It is on this site because resistance training is the main defence against the muscle loss GLP-1 medications cause, and this is the cheapest legitimate way to do it — against Tonal at nearly $7,000 over five years for the same physiological job.

Why This Belongs on a GLP-1 Site

Losing muscle alongside fat lowers your resting metabolic rate, which makes maintaining your new weight harder and regain more likely — and regain after stopping a GLP-1 is the norm. Our maintenance guide covers why body composition, not scale weight, decides what happens after.

Almost every provider we review sells the medication and nothing else. The training half is on you, and the barrier for most people is not motivation but access — a gym membership, the intimidation of a weights room, or the cost of equipment. A $135 strap set removes all three.

Angle Scaling Is the Feature That Matters

A suspension trainer adjusts resistance by changing how far you lean into the straps rather than by changing weight. Stand more upright and a row is easy; walk your feet forward and the same movement becomes hard. Nothing to load, nothing to buy, infinitely adjustable between the two.

For this population that is close to ideal, for two reasons. First, many people starting GLP-1 treatment are deconditioned and cannot perform a bodyweight press-up or pull-up; suspension training lets them do the same movement pattern at a fraction of the load and build from there. Second — and this is specific to being in a large calorie deficit — your available energy varies a lot day to day. With weights, a bad day means failing your prescribed load. With a TRX you take half a step back and complete the session at a lower intensity, which keeps the habit alive.

That adjustability is also its main weakness, which we come to below.

Price, and What It Replaces

The All-in-One at around $135 is the sensible buy for home use; the Pro adds durability aimed at commercial settings. Either way this is a one-off cost with no subscription — roughly what one month of mid-market compounded semaglutide costs, spent once. Thousands of positive user reviews suggest the hardware holds up.

What It Cannot Do

Progressive overload is harder to measure. Muscle retention depends on progressively challenging the tissue, and with weights you track that in kilograms. With a suspension trainer the variable is your body angle, which is difficult to quantify or repeat precisely. In practice you can progress by adding reps, slowing the tempo, or moving to single-limb variations — but you have to be deliberate about it, and most people are not.

Lower-body loading is limited. Suspension training is excellent for pulling movements and upper body; legs are harder to load meaningfully once you are past the beginner stage, since your body weight is the ceiling. Adding a pair of dumbbells or a kettlebell covers that gap cheaply.

Some movements demand shoulder and core control that a very deconditioned beginner may not yet have. Start with the easiest angles and build. If you have a shoulder injury history, get advice first.

Anchoring matters. These systems anchor over a door or to a fixed point. Install it exactly as instructed and check it before every session — this is the one genuine safety consideration with the equipment itself.

It Is Equipment, Not a Programme

Buying a TRX does not tell you what to do with it, and structured programming is most of what makes training work. Pair it with a plan — SHRED costs about $10 a month for AI-generated programming, and Future puts a human coach on it for considerably more. Even so, $135 plus $10 a month is a complete resistance-training setup for less than most people spend on supplements.

And remember the other half: training without adequate protein does not preserve muscle. See our protein guide.

Pros and Cons

Who Should Buy It, and Who Should Not

A TRX suits you if you are on a GLP-1 and doing no resistance training, which describes most people taking these medications. It is cheap, it works at home, it scales down far enough for a complete beginner, and there is no ongoing cost to cancel. Buy the All-in-One, pair it with a $10 programme, and add a kettlebell later for legs.

Look elsewhere if you are already training with weights and progressing — a TRX adds variety rather than capability — or if you need accountability more than equipment, where Future’s human coaching is the thing that changes behaviour. If you have significant shoulder, cardiac or joint issues, get clearance before starting.

Limitations of This Review

This review is based on retailer listings and independent coverage checked on 7 August 2026. Prices fluctuate with promotions — the All-in-One was recently discounted from about $180 to $135 — and we could not verify warranty terms, what each bundle contains, or weight limits. We have not used the equipment. The training and muscle-loss statements are general properties of GLP-1 treatment. Nothing here is individual exercise prescription; clear a new programme with a clinician if you have relevant conditions.

Frequently Asked Questions

Verdict

Most things we review on this site are optional. Resistance training is not: it is one of only two levers that determine whether the weight you lose is fat or muscle, and the difference shows up years later when you try to keep it off. A TRX makes that lever available for the price of a month of medication, with no subscription and no gym.

It is not perfect — progression is fuzzy, legs are undertrained, and it tells you nothing about what to do. But the realistic alternative for most readers is no resistance training at all, and against that comparison it is one of the best-value purchases on this site.
