Personally im not too concerned with training time , ihave to be different from everyone here I train each set and rep with full intensity and sometimes need a little longer rest between sets depending on many factrs including How much carbs ive had that day, how much sleep ive had, how many no doz (caffiene tabs) ive had (lol), stress levels , if i worked that day etc.
So i dont like to try another set unless im ready to give it my all and as you guys know squats , deads and heavy benches takes some mental preperation first im not going ot leave the gym till ive finished my work out so i normally train for 1-1.5 hrs i dont look at the clock to be honest then i do my 20mins cardio .....
so almost 2 hrs in the gym for (besides im ALWAYS waiting for the smith machine)
Funilly enough i can never get a bench when i need one but i can always go straight to the squat rack on leg day and its always free lol!
