"Exercise #4 (Spirit)" was performed in improvisation and has a different palette of instruments in comparison to the EP's other tracks, including Yamaha DX7 sounds and pan flute samples. The track is constructed around an electronically produced pump organ sound. Steve Shaw of "Fact" magazine wrote about the track, "as clicky mid-range keys amble daintily beneath, a butterflies-in-the-stomach sense of quiet excitement is drawn out by increasing vibrato and breathy shakuhachi/vox chord gestures." A rework of "Exercise #4 (Spirit)" was included on CFCF's collaboration album with Jean-Michel Blais titled "Cascades" (2017). "Exercise #5 (September)" is a synthpop "semi-cover" of the opening track on English singer-songwriter David Sylvian's album "Secrets of the Beehive" (1987) that's quadruple the length of the original piano ballad. Silver called "Exercise #5 (September)" a "fully realized" track in terms of instrumentation, consisting of basses, syncopated, single-reed-like synthesizer lines, 2-step-rhythm percussion that include claps and woodblocks, staccato piano notes, and vocals. He felt when he was making the track, it was being "a bit weighed down by ‘songness,’" thus he made a track featuring vocals that sung lyrics. Shaw compared Silver’s vocal performance on the cover to José González. As Jaber Mohamed wrote about the song's feel, "its upbeat tones speak of nostalgia for an idealism that no longer exists and an optimism of the coming future." "Exercise #6 (December)" was the seventh track completed for "Exercises" and the sixth in the track listing. Recorded in December 2011, it's the most minimal cut on "Exercises"; its instrumentation includes a piano, slow-attack synth brasses performing harmonies in the style of the LP "Amber" (1994) by English duo Autechre, and a mid-octave synthesized bell counter-melody representing snow. Silver said that it is about a "lost winter feeling" with "moments of tenderness, confusion, elation." Categorized by Williams as a downtempo track in the style of the works of Jean Michel Jarre, "Exercise #7 (Loss)" centers around a triple metre piano with sawtooth wave sounds and vibraphones that fade in and combine to a "cloud" around it, wrote Shaw.
