Power Grips are available in 5 progressive strengths and these rate as follows –

• PG100 The 100 is perfect for women new to weight training or grip training and is about 3 times the strength of those pathetic plastic grips that a baby can close.
• PG150 The 150 is the starting point for most men new to grip training and for women that rarely need men to open jam jars!
• PG200 The 200 is recommended for men that train with weight regularly and consider themselves to have an average grip.
• PG250 The 250 is rarely closed by people that do not train specifically for grip. Take it to your local gym and offer a beer to close it and there’s a good chance you will win the bet!
• PG300 The 300 will only be closed by strength athletes and grip specialists and for many people will take a lot of slogging away on a routine for months or years – we warned you! It is also a good executive paperweight.
