@dawn16 Glad you like the swings as well!
I chose 12/16 because I wanted to shoot for 1000 non stop and wasn't sure if I'd be able to shoot for that if i went higher.
If you see D2 & D4 i didn't make much progress doing the 16. So i decided to work with the 12 and get to longest continuous swings.
That then helped me make a lot of progress with the 16 in the end.
I've been sedentary long enough that i feel I've already earned whatever tools i need that make it fun for me to get and stay fit
- i have an 8, 2x12, 2x16, 20 and a t-handle that goes upto 40kg.
Cheers!
