Intercellular fluid circulation

The climate condition recently became better, so started I go on a bicycle for 30 minutes around my neighborhood. As a result my body condition improved especially because the recovering the liquid circulation in Leg Muscles and Orthostatic Spine Muscles. I don't recommend any construction of any body muscles by massage, because peripheral vascular around or near the muscle  are relatively easily destroyed leading to connective tissue hemorrhage.
Also the task for any muscle should work by shrinking, so the liquid circulation should be recovered by shrinking movement, not by mechanical rough massage action.
