I'll say on this the same as I say about crossfit.
Worse for gains than weight training, worse for cardio than cardio. The best way to combine both.
You have pointed out the biggest benefit of this style of training: Some people really really like it. From the fact that it is a trope that crosfitters talk about it all the time, I take that crossfit is really good at getting people to stick to the habit. I have recommended it to people whose main worry was "I don't know if I'll enjoy lifting weights that much".
The buzz is real
Depends on how off the beaten path you go. I can give for each of the movement patterns above my best recomended exercises, and how good they are compared to the gold tier.
[legs] : Lunges, Sissy squats, single leg squats and so on, if you add some weight to your back. I think these are great. Kind of annoying, and yo might only have one or two you are in the correct strength range to do.
[side delts]: Pretty much no way to train without a heavy thing you can hold in one hand. One set of adjustable DBs solves this.
[H pull]: Inverted rows are the only thing you can set sup, but... (read more)
Yeah. Progression will be really weird when you start by yourself.
Sometimes you'll be 20% stronger than last workout on the same exercise, sometimes 20% less (because you might have improved your technique).
If you are not, on average, getting stronger, you are probably not gaining muscle. Don't goodhart, letting your technique focus slip away.
Progression changes a lot from one exercise to the other. You can probably add 5lbs every time you deadlift for the first 3 months. However I've been doing DB Lateral raises for 3 years and I'm about to move on to the 20lbs.
My practical advice?
Those are great goals.
If you want to be "lifting your husband" strong, look up the starting strength squat and deadlift guides.
For upper body exercise suggestions, I think the list above is great.
For injury risk, I would really not worry, given the injury statistics are so low, and they are from people who DON'T focus on technique. The median gym goes is a 30yo guy swinging as much weight as possible around, and he's mostly fine.
As far as technique goes, define failure as "I can't do another rep without changing technique" and you reduce your chance of injure drastically.
For the exercises you're doing now, I'd say there is a lot of "redundance /... (read more)
For "optimization" I totally agree. This was not the goal here, but yeah I think if you can only do one you should lift, as it will improve your cardio to above baseline levels, but doing both is probably better than just lifting
You can find videos where girls deliberatly flexing can evoke bad reactions, but those same girls are totally fine when not flexing.
I have seen one example (so infer many exist) of a very gifted chinese lady living in the us who was quite muscular, and her wedding photographer photoshoped her legs to be skinnier. I have no idead how cultures other than the western monoculture operate with this, and probably should make it clear my statement is somewhat tonge and cheek, or add this nuance to it.
The thing to keep in mind is, lets say with 10 years of dedication you could get to a place where you'd be "too muscular".
1 - You'll notice before you get there and just stop. Muscle growth is extremelly slow
2 - You can reverse. 2 months of not training and dieting will take a lot of muscle off
If your gym has a good selection of machines, you can totally get really jacked just using them, see my above comment for Barbells vs Dumbells. My first questions to you would be how you're training your legs and abs since machines for those can be rarer.
I should double down on the point that injury should not be on my mind. Here are some factoids since I can't tread them into a coherent narrative very quickly:
* When the median american lifts weights, aka someone who is much more careless than yourself, he gets injured way less often than in any other sport.
* Even for injuries that happen in the gym, accidents like... (read more)
There is no broad difference. This is also true of the machines vs free weights question. Many trials have investigated this, and if two exercises have the same general movement pattern and are hard in the same way (e.g. a legpress and a squat), expect them both to work the same.
Some extra considerations:
* If I want to do a squat or deadlift patter, and I'm not a beginner, I'm going to be using inconveniently heavy dumbells.
* If I want to train my side delts with a barbell, I got maybe one good option (upright row)
And for each individual exercise I can probably talk your ear off about nuanced improvements with one or other.
If your question is something like "If I only ever use dumbells, can I get 90% of my theoretical max gains? " I'd guess yes. Use your creativity, google, and good sense to find exercises that challenge you as you advance.
The literature is inconclusive. We have many trials comparing training to failure to leaving sy 2 reps in reserve, and meta analysis on top of that. I can for sure say the improvement, if it exists, is very small.
The upside for a beginner of not going to failure though, is that going to failure makes you much more likelly to use bad technique, hindering your hability to properly learn good technique. Every rep you do with bad technique is very counter productive.
My current model for people who already have very well established technique is: Failure maximizes growth per set, but total growth is maximized by doing more sets not to failure.
Who this post is for? Someone who either:
I think that holds here. These are not statistcs from well controlled studies, just observational statistics from general folk, how often they report getting hurt while lifting weights
