Please help me choose one!

Need advice on choosing a gym as I am stuck between these 3 options

1. Sky Fitness: 12k/month membership, 30k trainer charges
2. Life Fitness: 6.5k/month membership, 30k trainer charges (negotiable)
3. Bahria Active: 50-60k/quarter membership, 25k trainer charges

Which one would you go with, and why? Any experience with these gyms would help.
