On day 13 Front raises are pictured as single arm, but then in the text it is said to switch to single arm if too hard. So it probably should be both arms raised.

Good catch, thank you! The poster is right - the front raises on Day 13 are alternating, one arm at a time. The text was describing the two-arm version so we've fixed it to match the picture :thankyou:
