Full body workout is fine for like 1 -2 months, then you should do splits and you can also do the splits on machines, no problem.
I personally never liked full body routines but most people I have talked to think that it's a good way to start.
if you are doing full body dont do it on machines
the whole point of starting out with full body workouts is so you can focus on compound movements. working out with machines completely negates that
I doing the same reps and sets on all what I need exercises
I think free weights are better, it will train more muscles.
For example squats will train abs, back, legs all at once, so u get a lot of work done with 1 exercise.
In my experience I fatigue faster with full-body training, because when u start to add some weight you spent the energy fast, at least in my experience.
I prefer splits after a few months of full-body but u need more time if u gonna do splits.
Please don't ask hltv for these details
Only ugly people work out
on machines, do cycles rather than doing the same exercise three sets in a row. So do like 5 or 6 different machine sets, then take a rest, then start at machine 1 again, so you at least hit the stabilzers with fatigue and multiple angles.
you could even just forgo the machines and do cycles of body weight exercises, like 10 squat jumps, 10 lunges each leg alternating, 10 step ups each leg alternating, 20 pushups, 10 squat jumps, rest. set a goal time, and complete the cycle in lets say 90 seconds
at the end of the workout, spend a long time stretching, then go eat immediately
do not do machines only workout
free weights (barbell + dumbells) are the most effective
machines should be used for isolation excercises only, with main focus on compound movements
Honestly, as someone who did a volume heavy version of 5x5 3x week for 6 months, before going onto 2x upper/lower week and then playing around with 2x Push/Pull/Legs week, Upper/Lower splits are the best use of your time AND energy. Doing an actual useful fullbody strength and/or hypertrophy workout is going to take you at least 2 hours, with warming up for big exercises like squat, dead, ohp, bench, barbell rows, pull ups, small accessories. In upper/lower you might just do
Bench - OHP+Chest Supported Row - Incline DB+Lat Pulldown, arm/shoulder isolation exercises.
It will take you the same amount of time as 3 full body workouts, but you will be able to do more total volume and have to spend less time warming up. The total quality of the volume might be slightly lower, but overall its a much better way to spend your time and energy, while still training frequently enough to actually improve.
