This study will be randomized controlled trial with non-probability purposive sampling. Study conducted among post CABG patients. Sample size will be 56, 28 in each group. Outcome will be measured by using 6 minute walk test, Spirometry (FVC, FEV1/FVC and PEF), Functional Independence Measure.

This study will be randomized controlled trial with non-probability purposive sampling. Study conducted among post CABG patients. Descriptive analysis will be applied. Data will be collected from Rehmatul lil Alameen Institute of cardiology Lahore. Sample size will be 56, 28 in each group. In addition to the routine Phase 1 cardiac rehabilitation for experimental group the exercise protocol consisted of 10 minutes of warm up, elastic band strength exercise protocol (30 minutes) and cool down (5 minutes) so that an exercise session lasted about 45-50 minutes, exercise will performed circularly 2 sets, 10 repetition with a 2 minute rest after each cycle and monitored the performance of exercise for 6 days. Resisted band exercise are Extending thighs, Closing thighs, Opening thighs, Bending thighs, Dorsiflexion, Plantarflexion. For control group routine Phase 1 cardiac rehabilitation only. Outcome will be measured by using 6 minute walk test, Spirometry (FVC, FEV1/FVC and PEF), Functional Independence Measure.
