No, I don't think so.
The Earth's density is 5.51 g/cm³.
For comparison, a baseball has a density of 1.3 g/cm³.
Even just the Earth's surface crust has an average density of 2.7 g/cm³ (it's more dense under the ocean)
Unless you can compress a baseball with your hands, you're not making a dent in the Earth.
The only way it would work would be if your strength increased proportionally with your size, which isn't the case normally for humans (someone 20% taller than another person isn't necessarily 20% stronger than them).
it is worth noting that density is not the only factor. wet sand or mud will also have high density (not as high as earth, but still), but your ability to crush it will be drastically different.
can you use tools in that scenario? do you have fix point available? can you take another planet and smash them together until one of them breaks? 😆
