Supplementary training devices such as Gripmaster's, Warm Up Putty and Grip Savers have really caught on in the last few years; they're great for getting that forearm pump when out and about. Read the Rock + Run 'Gripmaster Training Tips' article here.
As well as training, such devices are good warm up tools and can form an effective part of your injury rehabilitation scheme. For more information on using training devices as recovery aids, view the Rock + Run article 'Finger Injuries and Treatment' here.
We also stock a wide range of brushes (here). Brushing holds removes moisture, grease and dirt which can be vital for maximising your chances on your project.
