Working the heavy bag at the gym I burn a lot of calories. However, when travelling, which is a considerable part of my life, I won't be able to bring one with me due to A) Weight B) opportunity to hang it.
What equivalent equipment should I carry to substitute it? I expect that it fits in any flying luggage allowance. That is, it should not weight more than 10 pounds (and that's already a lot).
Could a water punching bag be of any use if you can't hang it? I was thinking about a kind of mixed exercise, lifting the bag and punching (hooks and jabs) it a couple of times in the air.
