This is a form of superset training, training opposite muscles on the upper body is important for balance, I normally complete one of these sessions per week, two exercises, three sets of max reps. When running I normally pop the resistance band in my pocket and stop to complete an upper body workout on route, it's easy to find a bar or in this case a tree guard, always check the surface is smooth first and watch out for nails in the wood.I completed these exercises both with a medium strength resistance band .reps x 40 and sets x 3 = 120 reps of tForward fly chest press Muscles; Chest pecs, shoulders and traps.1.
