No bands or resistance?

Trick is to use gravity….

Jumping over objects

Jumping onto high blocks

Development in to single leg hops

Single leg jump for height

Single leg bounding, which is basically running.

Kneeling jump.

All of the mentioned above make use of your own body weight and gravity. The higher the box the more force required.

Jumping down also uses gravity. The higher the drop the greater the loading. DONT go jumping off roof tops!!

Landing with isometric holds can also further develop and maintain strength levels.

If you are looking to surpass your leg strength plateau while in isolation these are some methods.
