Nice one man!
It can really be a great workout...especially when you take on a few hills.
For myself, Anabel is so small (maybe only 25 pounds), and it can be tough sometimes. I imagine 2 larger lads is a grind.
My problem recently has been some hand/wrist numbness. (One-handed push...two-handed wheelie to turn).
All things considered, rewarding and fun!
Yeah, it's not too bad considering the weight you're pushing; I figure it was likely 80-90lbs since the boys are both over 30lbs each. My problem is the tracking and correction I have to make. I'm sure there's a way to align it, I'm just too lazy to figure it out :)
