In the promotion of sports performances can be developed by improving the basic fitness factors through counterforce exercise. Leg and back strength is one of the components of physical fitness which can effect by the counterforce exercises. The present study was undertaken on 32 male runners of Amravati (M.S). Who were equally divided on random basis as experimental group (N=16) and control group (N=16). Leg and back strength was measured using leg and back lift dynamometer before commencement of training programme. During the experimental period the subjects belonging to the experimental group were given counterforce exercises for a period of eight week. Final test was conducted after eight weeks. The data shows a significant improvement in the leg and back strength ability test as a result of counterforce exercises practices. Significant difference is noticed between post test data of the experimental and control group. Thus it may be concluded with justification that counterforce exercises for eight weeks bring significant changes in leg and back strength ability of middle distance runners.
