Bodybuilder and powerlifter Tuan Tran demonstrates another effective exercise without a gym. In this video you will see him do some standing tricep kickbacks with gallons of water. Tuan explains: "Keep your arm tucked into your side at a 90 degree angle. Slowly extend your arm out and keep your elbow in. At full extension of the movement, make sure to keep a little bend in your arm and all the tension on your tricep muscle. Slowly lower the gallon back to the starting position. Repeat with your opposite arm." Watch the video:
