So basically just mix it up? Do heavy 1 week then light. I'm doing this for basketball. I want to jump higher and run faster.
Yes, but not on a weekly basis. You want to stay in a phase until you peak. Others believe in constantly mixing it up. I don't.
What I mean is you should keep on lifting heavy weight up and until you start peaking. That's when your body is adjusting to that workout and is not growing and is not going to grow and handle more. For example, you are improving through the weeks but you end up maxing out at 225 lbs. squat. You really aren't going to get farther doing the same thing. So change it up. And if you are doing explosive drills and plyometric exercises; and your vertical leap is growing little by little, but you peak out at 30 inches", then it's time to change it up.
As for basketball, I would recommend barbell squats. Form is very important. Don't squat down onto a bench. Have a mirror in front of you. You need to see your depth and go up when you've gone low enough. Using a bench under your butt to gauge depth can be a problem. You can injure yourself if you hit the bench too hard. And when you are dealing with heavier weight, you can herniate your disc pretty badly.
Don't put on more weight than you can handle. Increment the weight you use in 10 and 20 pound increments.
Deadlifts are good. Bad form can hurt your back. It requires you to partially scrapping your shins with the barbell so you aren't to far over your feet. If you are uncomfortable with this, you don't need to do this. I would recommend doing hang cleans as an explosive movement. Don't need to or want to do one rep max on this.
Skip leg curls and leg extensions, where you are seated or lying down and flexing at the knees.
Calf raise exercises are good too. Don't put on so much weight that you aren't able to fully go through the range of motion. Doesn't matter whether you are seated or standing, both type of machines work.
