After moving to Sweden, Chimaev wrestled at multiple clubs, including BK Athén.[26] Considered one of the best freestyle wrestlers in the country,[27] Chimaev won a gold medal at the 2016 and 2017 Swedish Freestyle National Championships at 86 kilograms, and in 2018 he did so at 92 kilograms.

In an interview with ESPN, Chimaev claimed he was inspired to start training in MMA during a night at work where he took a 15-minute break to watch the Aldo vs. McGregor main event. Chimaev stated, "I was watching his [McGregor's] fight. I was watching him fight Aldo. I was sitting in night and was working. I was taking rest for 15 minutes and watched his fight. I always look at that like if the guys make so many money like millions and this stuff, why I can't do it now. I'm a fighter, I'm a warrior and I have something special inside me. I had to find some way and take out this to show to the people."[32]
Between September 2017 and April 2018, Chimaev had three amateur MMA fights. The first of them was against future IMMAFWorld Champion Khaled Laallam, whom he defeated via submission in the second round.[33] He won his following two amateur fights, one by submission and one by technical knockout, completing his amateur career with a record of 3–0.[34]

In an interview, Chimaev revealed he trains up to five times a day on the peak of training camps, and two to three times when he has no fights coming up.[105]
Chimaev often utilizes his freestyle wrestling in his fights to get his opponents to the ground.[106] Once he is on top control, he employs different techniques to gain control over his opponents and land heavy ground-and-pound or seek submissions, while forcing his weight towards them.[107][108][109][110] His grappling is very often compared to Khabib Nurmagomedov's, due to the similarities of the techniques, such as the handcuff lock and hooking the legs.[111] Regarding strikes, Chimaev landed 192–2 in his first two UFC bouts utilizing this strategy.[112] Chimaev also proved its effectiveness on the regional circuit as well, with a quick win over former two-time GHSAwrestling champion Sidney Wheeler after taking him down with an outside trip.[113]
In addition to his grappling abilities, Chimaev will also strike in his contests.[114] Although his striking is still relatively unknown and untested, it involves heavy knockout power from the orthodox stance while utilizing basic boxing and mixing up kicks. He also uses his wrestling to set up his strikes by feinting different takedowns and vice versa.[113] By using his striking, Chimaev has been able to knock out UFC veteran Gerald Meerschaert in 17 seconds with a single punch.[115] He has previously used it to drop past opponents on the regional circuit, including former combat sambo World Champion Ikram Aliskerov.[116]

Chimaev is close with fellow mixed martial artists Darren Till and Jack Hermansson.[122]
Chimaev is close to Chechen leader Ramzan Kadyrov.[123] Kadyrov gifted Chimaev a Mercedes-Benz, which he crashed months later.[124] Kadyrov also allegedly convinced Chimaev to not retire in March 2021 and go back to Chechnya, which led to speculation on the media on whether Chimaev had been forced to do so.[125][126] Chimaev has sparred with Kadyrov, and appeared in multiple photoshoots with Kadyrov.[123][127] In 2022, Chimaev began training Kadyrov's two teenage sons, Zelimkhan (Ali) and Adam. He was in Ali's corner at his professional MMA debut at ACA 150 in December, accompanied him to UFC 280 in Abu Dhabi, and took him to train to Tiger Muay Thai in Thailand.[128]
Chimaev was present during a livestream in which Kadyrov threatened to kill a minor who criticized his repressive rule.[123][129] In March 2022, Chechen dissidents criticized Chimaev's continued association with Kadyrov due to his repressive rule of the Chechen Republic.[123]
Chimaev got married on 21 May 2022, in Chechnya and the wedding was attended by Kadyrov.[130][131]
