Hi I had a cheap personal training session with 2 of my house mates this week. It worked out only 30 pesos each for an hour which I thought was pretty good value compared to what else I have seen advertised in my gym! We trained out doors in the Palermo park which was nice as the sun was out...damn cold though! We used cones, bands and some weird thing that hangs from a tree. The trainers is a guy from the UK - he is qualified and made the session interesting and fun. Us girls needed the motivation due to the weather! His email address is buenosworkout@gmail.com. I think he does private sessions if you want one individually but personally I thought it was more fun being with my mates (again for motivational purposes) and plus it was cheaper!
