Two 13' x 1" ratcheting tie-downs: $21.98

2' x 1" PVC pipe for handles, cut to fit: $1.72

Exercise suggestions and routines free on TRX's own site as well as YouTube

Even if you buy TRX's own door anchor (how does it anchor?? I can't figure it out by looking at it) ... and even if you pay a cobbler to sew the handles on rather than just tying them ... I'm seriously not seeing $200.
