I need a good f2p strength pure training spot (Perfect Fighter)

I have been looking around, but just can find anywhere to train thats good exp. I trained on hill giants and got 18k exp/h, and 35k gold/h. The problem is that during the day hill giants get packed, so i get much less then that. I am using Perfect Fighter, and i am a strength pure. I am level 53 with 40 attack 68 str 58 hits. I do not want to train at S.O.S, and thats where most places say when i search. I would like to be able to get a decent amout of gold as well as exp. I would like input from everyone! Thank you in advance.
