This Buff Physique Pokémon GO Counters are important to know if you want to get through the random Rocket Encounters.
When you battle Team Rocket Grunts, they'll use a semi-randomized team that will be difficult to fight if you don't have the right counters. Luckily, you'll know which type of team the Rocket Grunt will send out when they taunt you. You can then select the right Pokémon for the encounter.
This Buff Physique Pokémon GO Counters
When the Rocket Grunt says "This buff physique isn't just for show!", it means they'll send out a team of Fighting type Pokémon. This one is pretty easy if you exploit the weaknesses.
Fighting type Pokémon are weak to Psychic and Flying type attacks. A good Alakazam and Mewtwo will easily sweep through their team, especially since they don't use shields in battle.
Flying Pokémon are good to use as well, just watch out for dual types that might have a disadvantage against Fighting moves. Fighting moves are strong against Ice, Rock, Steel, Normal and Dark type Pokémon.
Ghost Pokémon also heavily resist Fighting type moves in Pokémon GO. Ghost types that can learn Psychic type moves like Gengar can also do well here.
