This is a tidbit for kettlelbell lifting from a wellness standpoint. For someone who has blood pressure or cholesterol or bad knees this concept of fitness with kettlebells for these people is a perfect fit. My feet never leave the ground(minimize impact). I never clench for a submaximal weight.
The amount of tension for a lift is learned through repetition.
The discretion should be based on the ability to do very high reps with light weight in the beginning to get the form down.
I tried to run and felt pressure in the jaw area. Not pain but definite vibration. So I stopped.
From a standpoint of coming back from a surgery kettlebells reigns supreme especially where avoiding trama is concerned. If you go light enough if shouldn't be a problem. I can't run but I can lift 2 24kgs kettlebells. After what I had been through I wouldn't do what I thought was risky. Any problems, I would stop. I want to come back as fast as I can. In my experience that means that I want to come back as safe as I can. I want to get the max benefit for my workouts.
