I want to get my legs stronger so I can jump higher. Would ankle weights help me achieve this? If not, how could I improve explosiveness?

This question doesn't belong here.

Ankle weights do not help much. If you want to train explosiveness you should be doing squats, deadlifts, etc. You have to generate a lot of force to train the high threshold motor units (HTMU's) that control explosive movement. Since the equation for force is

F=ma

Where m is the mass and a is the acceleration, you train with high force with heavy weights, and/or fast movement. If you have more questions post in the "weight training" or "personal training" section.

How about isometric exercises?

Isometric exercises train the muscle contraction at a certain point. It's time under tension stuff that doesn't get someone much faster or stronger unless they're at a very basic level of training where just about anything will get them faster or stronger

Here is how:

There are number of things you can do. Some of the best exercises that come to mind are:

crouch - stand. This one is very basic but effective exercise. What you do is simply get in a standing position, crouch down, and get up with your arms extended if front of you. Do that 50 times to complete a set and about 3 sets a day. Rest about 2 minutes between sets

jump rope - of course, I can't leave out this one. there is no need to explain jumping rope. I'll just add that you can try to switch legs when jumping. For example jump for 30 seconds with one leg then 30 secs with the other and then immediately go with both legs. And if this is too advanced for you, you can train with your own numbers of reps. Then as you get better gradually increase the numbers.

stand under the rim and try to touch the net (if you can) with your head. So that means that when you jump, you'll put down your arms and just go up with your head. Then, as soon as you touch the ground jump again. do this, ahemm, 10 times to complete a set and 3 sets a day would be enough.

there are so many exercises to put here that really work.

On my website, I have special page full of free tips on jumping higher. Feel free to check it out:

Jumping Exercises

In order to jump higher:

1. Leg work (Squats, dls, lunges, leg press) The squat is the most important one not just because it's a great exercise that adds strength and mass to your body, but also the squat movement resembles the jumping movement to some extent.

2. Plyometrics

strapping weights to your ankles will make you jump lower actually, since it will make you heavier meaning it will then take more power to make you jump the same height you could without them..

Start some hill running, or some HIIT on stairs. The explosive power you gain is outstanding, and running uphill forces your body to run correctly (less chance of injury)
