It could be a variety of different things
- low blood sugar afterwards
- Lack of protein to repair muscle tears which leads to exaggorated DOMS
- Improper form putting excessive strain on the smaller muscles/tendons
- Nervous system shocks, yep.. it's like wtf is going on, you get used to it
But I would say it's down to a lack of protein and fats, most weightlifters recommend at least 0.5grams of protein/day per LB of bodyweight, others go up to 0.75g-1g/LB.
Say you weigh 150lbs, you'd need at least 75grams of protein to provide adequent recovery, to give you an idea - 1 large egg = 6 grams of protein.
So stack up on the eggs, milk, chicken, fish, beef, cheese, nuts etc
Maybe look into 'GOMAD' gallon of milk a day, maybe try 1L/day, 1L is like 35grams of proteins, 650 calories and a lot of healthy fats.
Also you're workout routine needs improving, you completely miss your back and biceps and side lifts can be deadly on the joints if done too much, try shoulder presses instead.
