Quick Answer: The best way to turn stand-up paddling into a real workout in 2026 is to add Suploops resistance bands — a set of 5 paddle-mounted bands (10-50 lb, combinable) that slide onto your paddle shaft for on-water rowing and press exercises — alongside Gymenist waterproof ankle/wrist weights (about $19.99, confirmed direct on gymenist.com) for extra resistance during balance work. Both matter because research shows leisurely paddling alone often isn’t intense enough to count as real cardio exercise — these accessories are how you close that gap without changing boards.
Most people assume paddle boarding is automatically a great workout because you’re standing on an unstable surface. It can be — but an ACE Fitness-sponsored study found novice paddlers on a leisurely outing averaged just 55% of their maximum heart rate, short of the roughly 64% threshold generally used as the entry point for cardiorespiratory benefit. The accessories below are how paddlers turn a pleasant float into training.

1. Suploops Resistance Bands — Best for On-Water Strength Training
Suploops Resistance Exercise Bands
- Set of 5 fabric-free resistance bands (10, 15, 20, 30 and 50 lb) with reinforced self-loop ends that slide directly onto your paddle shaft in any position — no clips, carabiners or weak-link attachment points to fail mid-workout.
- Bands can be combined for 13+ distinct resistance levels from 10 lb up to 80+ lb, and the whole set weighs under 16 oz, packing into a nylon drawstring bag that fits in a deck bag or dry bag.
- Designed specifically for SUP use: the bands float if dropped, don't add meaningful drag while you're actually paddling with multiple bands on the shaft, and double as an improvised paddle leash or sling when you need both hands free.
This is the only resistance-band product built specifically around a SUP paddle rather than a doorframe or a squat rack, and that’s exactly why it’s the top pick here. Standard land resistance bands need an anchor point most boards don’t have; Suploops solved that by making the paddle itself the anchor. The self-loop ends mean you can add or remove bands one at a time between exercises without re-rigging anything, which matters when you’re balancing on moving water and don’t want to fumble with a carabiner.
Buy it if: you want genuine strength training built into your paddling session, not just the incidental core work of staying upright.

2. Gymenist Waterproof Ankle/Wrist Weights — Best for Balance and Core Work
Gymenist Waterproof Ankle/Wrist Weights
- Confirmed direct on gymenist.com at $19.99 for a pair; sold in weight increments up to 4 lb per weight, adjustable hook-and-loop strap fits either ankle or wrist.
- Neoprene-and-silicone construction built for swimming and water-sport activities specifically — unlike dry-land gym weights, these are rated to handle a full dunking without the fill leaking or the strap degrading.
- Adds resistance to the leg and core stabilization work your body is already doing to stay balanced, and to arm work if you clip them to your wrists during a paddling-cadence drill.
The reason to specify “waterproof” here isn’t marketing language — it’s the difference between a product that survives a normal SUP session and one that doesn’t. Falling in is routine on a paddle board, and most gym ankle weights use a fill and stitching that isn’t rated for submersion. Gymenist’s pair is built the way pool and open-water swim weights are, so an unplanned swim doesn’t ruin them. At 4 lb max per weight, they’re a modest add — enough to make balance corrections and static holds noticeably harder without throwing off your stance on the board.
Buy it if: you want your balance and stabilizer muscles working harder without adding any hardware to the board itself.
How to choose paddle board fitness accessories
- Confirm water rating before anything else. A land gym product like Bala Bangles explicitly says not to submerge it — fine for a warm-up on the dock, a poor match for actual on-water use where falling in is normal.
- Match the accessory to the muscle group you’re missing. The ACE-sponsored EMG data found the obliques lag behind the rest of the core unless effort is high — resistance bands push overall intensity up, while ankle/wrist weights specifically load balance and stabilization.
- Don’t let it replace your leash or PFD. Neither accessory here is a safety device; keep your leash and life jacket on exactly as you would on any other session.
- Start with one accessory, not both at once. Adding paddle-mounted bands and ankle weights on the same first session makes balance harder to judge — test each separately before combining them.
- Pack size matters on an inflatable. Both picks here pack small enough to fit in an existing dry bag alongside a pump and repair kit, no extra deck space required.
Paddle board fitness by the numbers
- 45% MVC — the maximal voluntary contraction threshold the rectus abdominis and erector spinae stayed above at every effort level in an ACE Fitness-sponsored EMG study, showing core engagement happens even at an easy pace.
- 60-125 kcal — what novice paddlers burned in a 30-minute on-water session in that same study, well below the 270-300 kcal experienced paddlers hit at higher effort in lab conditions.
- 55% of max heart rate — the average a novice paddler reached during leisurely on-water paddling in the study, short of the roughly 64% threshold generally used as the entry point for cardiorespiratory fitness benefit.
Once you’re training harder on the water, the rest of your setup matters more too — see our best paddle board for yoga picks for the low-impact end of on-water fitness, our best touring paddle board guide if you want to build cardio through distance instead of resistance, and our paddle board accessories hub for everything else worth packing.
The bottom line
Add Suploops resistance bands if you want genuine strength training layered onto your paddling session rather than relying on incidental balance work. Add Gymenist waterproof ankle/wrist weights (about $19.99) if you want your stabilizer muscles working harder without changing anything about how the board handles. The ACE-sponsored research is the honest takeaway either way: a relaxed paddle is a nice float, not necessarily a cardio workout — these two accessories are the cheapest way to close that gap.
