I have worked out at allot of them.

One misconception is that it is a good place to pick up girls. I would discourage you from trying this. the gyms here are very expensive more then the states and that means that the hot chicks you see normally have a boyfriend or husband paying for it. It is a luxury that most colombian women do not enjoy. Jealous boyfriends or husbands you do not want to deal with here in Medellin.

Now can you see some of the hottest chicks in Medellin at the gyms, oh yeah for sure but you are better off focusing on your workout.

Best gyms
Bodytecks are the most expensive and in particular bodyteck viscaya in poblado has some of the hottest chicks.

Las Vegas Bodyteck has the best views.

Forma las americas in Belen is the largest gym and the first super gym, lots of equipment and reasonably priced vs bodyteck, forma envigado probably the most pros and prepays in medellin workout there as envigado is where they congrugate. it is smaller and more crowded in peak hours.

Forma in Poblado small and not worth going to near exito unless you live close by.

there are also free places outside to workout like in parque lleras where you will workout next to poor colombian men. Kinda like muscle beach venice but poor version with concrete barbells and pullup bars and outdoor benches.

The estadio area has a workout area near the olympic pool and you can get there on metro.

also a large outdoor workout area next to pool and deportiva in belen, very crowded with colombians, you can also work out at public pool in belen next to airport and they have trails for skating and biking and walking.

dont forget to walk up the stairs if you live in a edificio with many levels
