Think you need the budget of the military or a megacorporation to make an exoskeleton for heavy lifting? Nope -- all you need is some standard parts and the know-how to put them together. James Hobson (aka The Hacksmith) has finished a homemade robotic suit whose pneumatic cylinders let him curl 171. 5 pounds' worth of cinder blocks with relative ease. While it's not the most sophisticated setup, it's only running at half pressure and could potentially double the load with a compressor upgrade. There's a work log at the source link if you're eager to see how this project came to be. With that said, you'll want to be cautious about trying this yourself -- there aren't any leg supports so far, and those blocks aren't exactly harmless. If you're like me, you'll probably feel safer watching Hobson's demo video below.
