Placebo Comparator
Maraviroc (Celsentri)
Placebo
Maraviroc (Celsentri) will be administered to this group. Participants will be administered a dose of 300mg to be taken twice per day for the duration of the exercise intervention (8 weeks).
An over-encapsulated placebo, or "sugar pill" (so it appears identical to the trial drug) will be administered to this group. Participants will be administered the placebo identical to the 300mg maraviroc tablet for the duration of the exercise intervention (8 weeks).
