Your AcroYoga partners are busy being ordinary, upright humans. You've got an hour to train. So: handstand blocks or parallettes?
The main difference is what your hands do. On blocks, you have a raised surface with edges your fingers can work around. On parallettes, you wrap your hands around a handle. That changes the contact, the grip and the space available beneath you.
I'd start with the exercise you want to practise. It's much easier to choose equipment once you've got something specific to do with it.
Blocks: a different surface to balance on
Handstand blocks make sense when you want to explore balancing on a block surface, using finger contact around the edges, or working on particular handstand and press drills your coach has given you.
Our Elemental Handstand Blocks are handmade in Bali from teak, with cork bases, and sold as a pair. The range includes flat, angled and round styles.
Those shapes aren't just different looks.
They change the surface and hand position you're working with. If you're buying for an assigned drill, check which style your coach means. No need to order the whole collection and work backwards from there.
Parallettes: something to grip
With parallettes, the handle is the point. Your fingers wrap around it, and the raised position creates clearance for work such as L-sits, presses, handstands and conditioning.
The Elemental Wooden Parallettes are also sold as a pair, with teak handles and cork contact points at the base.
If your planned exercises need a handle and room underneath, these may be the more useful first purchase. Just don't confuse having extra clearance with being ready to use a deeper range. Start with work you can control; get guidance on unfamiliar entries, exits and progressions.
What actually carries over to AcroYoga?
Selected balance and strength work can be part of your solo practice. Neither tool recreates a partner's hands, movement or communication, though. A hold on blocks isn't proof that you're ready for hand-to-hand.
Sometimes the next useful session is a solo one. Sometimes the thing you need to work on only happens with your partner there. Be honest about which problem you're trying to solve before buying another piece of wood.
For ideas on connecting the two, have a look at our solo training guide for AcroYogis.
“Are parallettes better for my wrists?”
A different support changes your hand and wrist position, but comfort is individual. Handstand Factory discusses floor work, blocks and parallettes as different loading experiences in its article on elbows in handstands. That doesn't make one apparatus an injury-prevention tool.
Neither blocks nor parallettes are a treatment for wrist pain. Don't change the grip just to push through symptoms. Stop the provoking activity and seek appropriate professional advice; if you're returning from injury, make the training plan with the professional supporting your recovery.
Before you turn upside down
Check the equipment on the surface you'll actually use. Look for cracks, loose joints, movement and damaged contact points. Use a level, stable surface, clear the space around you and get instruction for unfamiliar inverted work. Cork bases don't make every floor suitable.
Both products come as pairs. A small detail, but worth checking when you're comparing equipment.
And if what you really need is support beneath the base during L-basing, that's a different job: The AcroBack is the relevant range. You don't need to build a complete home gym just because you enjoy AcroYoga. Pick the tool that gives you something useful to practise this week.
