 Is all muscle training the same?
I am doing isometric exercises ( Callanetics) and getting amazing results. I can say that I am sculpting my body 5 times faster than with regular muscle training with machines or hand weights. I have gain a lot of strengh and do it 6 days a week.
I have read this book that says you should do WEIGHT training to keep your muscle mass as you age, so I am confused. I can SEE and feel that I gained muscle with Callanetics. Are the muscles build differently or have different composition if built with resistance training ( weight) than with isometric exercises?
