I see your postcode LE65, not sure which Leicester Fitness First you would be thinking of. But I am a member of the one on Raw Dykes road right by the Walkers Stadium.
It's quite good, main reason I go there is I can walk to it and when I come home from uni for holidays and such I can use my same membership here too.
Depending what time you go it can get pretty busy on the free weights, cardio equipment gets rammed with the 5pm after work rush too.
2 sets of dumbbells, plenty of free weights, squat rack, leg press and about 6 benchs. So for freeweights it's fine. Only one benchpress bench and no decline bench but can improvise.
Plenty of machines too if you use them and they dont seem to get hogged as much. Others upstairs too.
I can reccomend it, from my point of view. However I solely use freeweights and ocasionally use cardio equipment (prefer to just run outside).
