Hexbar man bad, you are limited in what you can do with it. get an olympic bar and 160kg of weights for starters, or join a gym if you can't afford it.
Do Deadlifts, Squats, Bench Press, pull ups and Overhead Press. These are compound exercises and you will be working most of your muscle groups doing these. for a beginner a good starting routine is starting strength, 3 sets of 5 reps or 5 sets of 5 reps on most exercises, the last rep needs to be very difficult. If you feel like you are easily doing 5 repetitions you need to add more weight. Sets of threes are also good but again you need to be physically unable to do another rep after the three in a set. Train 3-4 days a week minimum & 5 days a week maximum, every training day you train your upper body and your lower body. Here is an example of my training day:
Bench press: warm up with heavy singles until failure, then do 5x3, then 5x5 and stop decreasing the weight when it becomes negligible.
Do pull ups until I physically can't pull myself up anymore (starting out, especially if you are pudgy, you will be unable to do them or do very little of them but you have to keep trying, no other way to work back)
Squat, warm up with 3x5, then increase the weight by 10kg and keep doing 3x5 until I can only lift it for 1 rep.
Do some dips until failure, usually 6x8
Train with a 80kg stone in my yard, shouldering it, carrying it and holding it for resistance training. The same can be replicated with farmers walks and bent over rows.
Training should take at least an hour, over the years mine has become 2-3 hours long.
>Is adding 10 lbs per week to my lifts reasonable? I do 1 set of 5 reps each deadlifts and 2 sets of 1 minute each farmers walks (both currently at 80lbs).
Yes, it is very reasonable. You will hit a wall eventually, but if you can take the weight keep adding more. Do 1 rep max deadlifts as well, as long as you maintain proper form. At least once a week load up the bar with enough weight that you can only lift it once and just barely while maintaining a good posture, then lift it over and over in 'sets of one' until you physically can't lift it off the ground anymore. You are not just training your muscles you are training your central nervous system and it gets used to lifting heavy shit trough shock.
Know that like 90% of the people lifting really heavy shit online, like 300+ kg deadlifts are on steroids. Hang around on /fit/ and go to a gym and you'll learn to recognize it, don't get discouraged if you see someone claiming an unbelievable transformation in half a year or a year, it is most likely a lying roider. But at the same time you can get a decent phisique with one year of training.
Combine both bodyweight stuff and weightlifting, taking from your posts you are probably a fatass that wants to become strong and big, bodyweight exercises become extremely good for building muscle when you are heavy, so combine them. But likely you won't be able to lift yourself until you've done some weightlifting first, IF you are heavy.
Go to 4chan /fit/ unironically, you will learn a lot more than here, people ITT don't know anything. /fit/ is generally a good point of reference for starting out, just take what they say with a grain of salt. They like to complain a lot and are whiners. The shit posted ITT is either girly shit or fitness fad shit, I can guarantee only like 2 or 3 posters in this thread actually train.
RESISTANCE BANDS ARE A FUCKING MEME, ANYTHING THAT ISNT LIFTING YOUR OWN BODY OR LIFTING WEIGHT IS A MEME. STOP WASTING YOUR TIME ON THAT SHIT! FOR BODYWEIGHT PUSH UPS DIPS LEVERS PULL UPS SQUATS FOR WEIGHTLIFTING SQUAT DEADLIFT BENCH OHP, EVERYTHING ELSE IS AUXILIARY AND YOU CAN'T ACTUALLY GET IN SHAPE FROM IT.
