chorus is negligible, the gauche 'Let's Get Physical' double entendres are eye-rollingly unsexy, and Minogue's delivery is too ladylike to deliver lines like, 'Feel the burn... Let me see you take it down. Let me see you take it up. Let me see you bounce, bounce, bounce, bounce... stretch it out baby.'" Kitty Empire from The Observer said that, lyrically, "It's so raunchy, it could just be an in-joke cooked up between Kylie and Sia Furler (who wrote the song, and exec-produced KMO). Lyrics such as 'feel the burn' suggest an STD, not ecstasy." Andy Gill from The Independent believed that "Sexercize" was an attempt to enter the American market with the contemporary use of dubstep. Lyrically, the song talks about sexual intercourse with a partner, basically referencing the sexercizing technique. Neil McCormick from The Daily Telegraph said that "Sexercize", "Les Sex" and "Sexy Love" had attracted "youth markets still obsessed with dating rituals." Alexis Petridis examined that "'Sexercize', which gets itself into such a muddle trying to find sport-related metaphors for sex that it starts coming up with phrases that convey something other than what you suspect they're supposed to mean. "I want to see you beat all your best times," purrs Minogue: well, if you're absolutely sure that's what you want, I can probably be at the "finishing line", so to speak, in about 90 seconds flat." Critical reception "Sexercize" received generally mixed reviews from most music critics. Joe Sweeney from Slant Magazine said that while "Sexercize" and album track "Les Sex" were forgettable, "but none that truly ruin the party. Even the dubstep outlier 'Sexercize' works as a counterpoint to the album's deeper themes; as Minogue's maniacally digitized voice repeats the dumb/wonderful portmanteau over and over, her commitment to sounding temporarily insane is admirable." Tim Sendra from AllMusic exclaimed that "Sexercise" rises above some really dorky lyrics to actually sound kinda sexy in a robotic R&B kind of way." Chris Bosman from Consequence of Sound listed it as an "Essential Track", describing it as a "low-key dubstep seduction". Negatively, Joe Muggs from Fact Magazine said that the song was a thumpy filler and said that "the ridiculous single – full of exhortations to 'feel the burn', 'stretch it out', 'beat all your best times' and well-oiled US dubstep gurgles and slithers – is low camp of the most glorious sort, turning every bro cliché into pure muscle
