My goal with this is increase upper body muscle.
I have eased on the massive walks but am resuming now as spring is here.
Well, the thing about lifting and doing all weights in general is that muscle has memory, and if you're doing the same exercises with the same weight at the same reps over and over you're just going to end up wasting your time, and likely getting an injury. I used to see this all the time at the gym, guys just coming in and doing the same thing every week over and over. It doesn't work. Or worse, guys carrying too much weight killing themselves doing raises/dead bugs/hours on crunch machines, trying to get abs and not understanding that you don't get abs from exercises you get them from being lean.
The way building muscle works is more or less by 'tearing'. Muscles tears and new muscle builds over the old, which creates mass or as the cool kids say these days 'gains'. The only correct way to do this is to lift until fail, which is something nobody should be doing along without someone to spot them if we're talking about free weights.
Honestly Declan for what you want to do, it's definitely worth investing in a cable weights system/multi-trainer if you don't want to pay for a gym membership/want to work out at home. You'll get far more value out of this and will be able to do a lot more exercises, and you'll be able to safely lift until fail without the risk of a bar crushing your windpipe or something because you don't have someone to spot you. They're very versatile and much better for targeting specific muscle groups than free weights also.
