Release tight muscles after training. Roll the peanut ball along either side of your spine, neck and shoulders, and use the single ball for your feet, glutes and smaller areas.

• Firm, lightweight EPP foam

• Choose an 8 cm ball, a 16 x 8 cm or 24 x 12 cm peanut ball, or the 3-piece set

• Small enough to take to the gym or on holiday

Avoid rolling directly over bones, joints or injuries.
