But this frequently produces lumps – precisely what you want to avoid. Use the shakers by Body Attack to create perfectly creamy, delicious and lump-free shakes. The shakers have a finely-meshed sieve to prevent lumps forming and also a measurement scale to guarantee dosage of just the right volume of liquid.
