I currently lift 3 days per week with Monday-Chest,shoulders, tris Wed back and bis friday legs lower back Abs each lifting day. I walk 2-3 miles on a treadmill tues,thurs,and sunday. I train karate saturday 2 hours and often another day during the week.
Heres my dilema: I am 56 years old and have hip replacement. I can squat again with no problem but running, bouncing and high impact stuff is out of the question. I am looking for suggestions for an alternative cardio workout (maybe videos or something) that would take about 30 minutes and get my heart rate to target zone. I can do it with treadmill but that sometimes gets old. I am toying with creating my own cardio workout with karate training basics (warmups, exercises, and kata) but would like some ideas. I don't want to do anything that would be detrimental to my lifting so circuits, calestenics, and kettlebell stuff is probably out of the question.
Any body got any thoughts/suggestions?
