Two things I hear constantly at jams, usually said quietly:
"I'm too heavy to fly."
"I'm too small to base you."
Both are usually wrong, and both stop people practising. So let's take them seriously instead of just saying "anyone can do acro!" and moving on — because that's not quite true either, and pretending it is doesn't help anyone.
What actually determines whether a pairing works
Not the numbers on their own. In rough order of what matters:
1. The base's technique. Bone stacking is the whole thing. A base with straight, vertical legs is transmitting weight through their skeleton into the floor — their muscles are steering, not lifting. This is why a well-trained smaller base can hold someone much larger, and why a strong base with sloppy alignment tires out fast.
2. The flyer's tension. An organised flyer feels dramatically lighter than a soft one of identical weight. Not slightly — dramatically. This is the single biggest variable in how heavy someone feels.
3. Proportions, not totals. Where the weight sits matters more than how much there is. Limb length affects leverage and reach. A tall flyer and a short base can struggle for reasons that have nothing to do with mass.
4. Then, some, the actual weight difference. It's real. It's just fourth.
If you think you're too heavy to fly
You're almost certainly not.
What's true: you may need a base with solid technique rather than a beginner. You may need a spotter for longer. Some dynamic skills may take more time.
What's not true: that you can't fly. I've based people across a very wide range of sizes and the ones who felt hardest were never the heaviest — they were the ones who hadn't learned to hold a shape yet.
The fastest thing you can change is tension. Hollow body work is free, needs no partner, and will make you feel lighter to every base you ever work with. Solo training covers it.
And when you ask someone to base you, just say it plainly — "I'm around 80 kilos, are you comfortable with that?" Direct beats apologetic. Most people will say yes, and the ones who say no aren't judging you, they're being responsible.
If you think you're too small to base
Also usually wrong, but with a real caveat.
Technique carries far more than strength. Small bases can hold big flyers when the stack is clean. What size does affect is margin — when a heavier flyer goes off balance, a smaller base has less room to recover before it becomes a fall.
So the honest guidance: build technique first, use a spotter longer, and progress slower on dynamic work. Not "don't." Just "with more care."
The bit nobody says out loud
Heavier bases often get quietly funnelled into basing forever and never get to fly.
It's rarely deliberate. It's just that at a jam, people pair by convenience, and the biggest person in the room ends up on their back all afternoon. If that's you and you'd like to fly: ask. Directly. Say "I'd like to fly today." People will make it work — it usually just hasn't occurred to them.
Same in reverse for very small people who'd like to base and keep getting handed to someone's feet.
How to make mismatched pairings work
- Spotters, more of them, for longer. The single biggest safety lever.
- Stay low. Get genuinely solid on the ground before anything standing.
- Static before dynamic. Impact forces scale with weight much faster than static load does.
- Shorter holds, more of them. Fatigue is what turns a wobble into a fall.
- Talk more than feels necessary. Both people should be narrating.
Where support gear genuinely matters
Heavier loads mean more force through the base's lumbar spine, and that arrives sooner. This is the situation where back support stops being a comfort item.
More load generally wants more height and a wider contact area — which is what Big Poppa exists for, versus the compact Go. If you're basing bigger flyers regularly on hard floors, that difference is worth having.
It won't fix technique. Nothing does. But it buys you sessions while the technique comes in — same as everything else in this practice. The full comparison covers the free options too.
The point
AcroYoga works across a much wider range of bodies than most people assume, and the limiting factor is nearly always technique, spotting, and patience — not size.
Be honest about what you're working with, get a spotter, go slow, and ask for what you want. That's it.
