ARO Muscelul Câmpulung

The club was originally founded in 1947 as Metalul IMS Câmpulung by Gheorghe Grosaru, a director at the Întreprinderea Metalurgică de Stat (lit. 'State Metallurgical Enterprise'), with factory workers contributing financially to support the team. It competed in the Argeș Regional Championship, finishing 4th in the 1954 season, 6th in the 1955 season, and 6th again in the 1956 season.

Renamed Muscelul IMS Câmpulung, in reference to the historic Muscel County, the traditional geographical area surrounding Câmpulung, the team finished 3rd in the 1958–59 season and 8th in Series I of the 1959–60 season.

In the 1960–61 season, Muscelul IMS won Series I, qualifying for the championship final, where it secured the regional title after a 2–2 away draw and a 4–0 home victory against Unirea Drăgășani. However, it failed to achieve promotion, finishing 5th in the promotion tournament group held in Sibiu.

The club was later renamed Muscelul UMM Câmpulung following the renaming of Uzina Mecanică Muscel (lit. 'Muscel Mechanical Plant'), and after a 4th-place finish in Series I of the 1961–62 season, Muscelul UMM, coached by Ion Lăpușneanu, earned promotion to Divizia C at the end of the 1962–63 season by finishing as runners-up in the Argeș Regional Championship.

In Divizia C, Muscelul finished last in the South Series of the 1963–64 season, but was spared from relegation due to the expansion of the third division. It then spent two consecutive seasons in the West Series of the third tier of Romanian football, finishing 9th in the 1964–65 season and 7th in the 1965–66 season, before competing in the South Series in the 1966–67 season, where it finished 13th and was relegated to the Regional Championship.

Muscelul secured a quick return to Divizia C after finishing as runners-up in the 1967–68 Argeș Regional Championship. The team then spent two seasons in the third tier, competing in Series IV, finishing 11th in the 1968–69 season before being renamed Unirea Câmpulung for the 1969–70 season, during which it struggled and was relegated after finishing 15th.

Following relegation, the club reverted to the Muscelul name and went on to win the 1970–71 Argeș County Championship, earning a swift return to Divizia C. Its stay in the third division was short-lived, as it was immediately relegated back to the County Championship after finishing 13th at the end of the 1971–72 season.

The first time they played in Divizia B was in the 1977–78 season when they barely avoided relegation, in the following one they finished on the 9th place and in 1979–80 they relegated back to Divizia C after finishing on the 15th place.

Muscelul returned to the second division after winning Series VI of Divizia C at the end of the 1984–85 campaign, under the guidance of coach Vasile Stan. The squad included Popa, Istrate, Stoica, N. Iosif, Lungeanu, Miuțu, Nae, Păun, Predică, Necula, Berevoianu, S. Iosif, Oiță, Pescaru, Vlăsceanu, Apostol, Pamfil, Coman, Grigoriu, Moț, and Preda.

In 1985–86, Muscelul competed in Series II of Divizia B under Ion Voica, who took over after eleven rounds, with Stan remaining as assistant, but the team was relegated after finishing in 15th place by the end of the campaign.

In the 1994–95 Divizia C season the team finished on the second place, behind Minerul Motru so in order to promote to Divizia B they had to participate in a play-off against ICIM Brașov but before it, coach Nicolae Tănăsescu was replaced with former Romanian internationals Ion Oblemenco and Nicolae Dobrin, the first as head coach and the latter as technical director. The play-off was played in a single leg and ARO won it with 1–0, the only goal of the game being scored by Sergiu Coman, the team used being: Heroiu – Jitaru, Gorgonaru, Dumitrescu, Durdun – Ioniță, S. Din (I. Bădescu), Eftimie, Cl. Mutu – Butaru (Procorodie), S. Coman. Shortly after the promotion Oblemenco and Dobrin left the club, also the team's goalkeeper, Laurențiu Heroiu was killed after being stabbed in a bar, however the team spent 9 seasons in Divizia B before relegating in 2004, a period in which their biggest performance was with coach Ionel Augustin when they earned the second place in the 1999–2000 season.

In the summer of 2019, after three years of inactivity, the club was refounded again, this time as Academia de Fotbal Muscelul Câmpulung, former Romanian international Gheorghe Mihali was named as manager and Roberto Ayza was one of the first transfers realized by the new entity followed by Iulian Tameș and Iulian Vladu among others. However, the 2019–20 season was suspended in March 2020, due to COVID-19 pandemic in Romania with Muscelul finishing in 3rd place.
