lifting for almost a year now and I was wondering if i should up my volume or not
You have already had a couple replies on this, none of which are wrong, but here’s something more comprehensive.
If you’ve been lifting for a year and asking this question it is likely that you’ve notice progress slowing down. This is normal as you will always adapt to the stimulus you’re subjecting yourself to, so you should change something if you want to see progress continue. Doesn’t have to be volume though, you can also change the movements you’re doing. Small changes like going from skull crushers to behind the neck dumbbell tricep press can change the angle and forces enough that you feel like a newbie again and growth returns. Research some common alternatives to the exact lifts you’re doing and try some substitutions. You’d be surprised.
People have all sorts of reasons for working out at home - so this may not apply or be possible for you - but if you can do it I recommend actually joining a gym. As a 1 year old lifter you won’t be horribly out of place, and you will learn a LOT. Just watching what other guys do will open up a world of knowledge and, once you’re somewhat of a regular, you’ll have people gladly sharing their tips and advice and all sorts of things that will propel you forward.
And to give a more direct response to your question, 4 days a week really is the minimum unless you have a super physically demanding job or are really seriously practicing another sport. I also think you’re light on sets. I always pick 5-6 lifts, then do 1 light warm up set of 15+ reps then 3 working sets of 10-12 reps where the last 1 or 2 reps is a huge struggle. Don’t worry about all this ‘failure’ or RiR stuff, just get though your 3 working sets feeling like you didn’t leave anything on the table. After my 5-6 lifts I’ll throw in some basic body weight movements to hit little stabilizers and abs like crunches, leg raises, that kind of stuff. Keeps your physique balanced.
I hope there was something helpful for you in there. No matter what you end up doing, just stay consistent and don’t stop (even if it seems like you’re plateauing for a bit) the fastest, strongest, fittest people are the result of the long term grind not any one routine or trick.
Great name BTW.
