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).
