NEVER do behind the head lat pull downs !! Do your cardio on seperate days, only a 5 minute warm on bike, treadmill etc on weights day.Rreacher curls ARE bicep curls, they are just done with an object ( bench ) & held at a certain angle throughout the lift.Chin ups & pull ups are for the lats..if you can't complete one, is there a assist machine at your gym ? ..There is the method of training eccentrically ( negative phase ) which would be to use a chair, grasp the bar & slowly & controlled, lower yourself down to the full extended position, jump back on the chair & repeat.A girl in my class was doing these to help her do a chin up effectively, as her muscles also were not strong enough for the lift.I personally did lat pulls till I got close to pulling my own weight, then each workout went to the bar & tried to lift myself as much as possible, until ONE day it happened & I've now gone from one chin up to doing 10 consecutively.Fygle is right, do the compound lifts before tiring your arms out with isolation work try something such as..
Lat pulls/squats or leg press
chest press/dead lifts or back extension
shoulder press/seated row
Bicep curls/Tricep kickbacks OR press downs
If you MUST do isolate hamstrings do ONE leg curl activity, the same with chest ONE activity.If you do not follow my suggestions, I can't help anymore, they call them fitness prescriptions because they are like a prescription a doctor would give you & if you take your medicine incorrectly it wont work, neither will the fitness.As for ramadan I know what it is & if you have any hopes of working out, eat after dusk, workout, then eat again & make sure there is protein, whole grains, vegetables & healthy fats in BOTH meals, eat again before the daylight.Good luck
