What is the absolute hardest workout/exercise that you've ever done?

Cross-country sking but not the groomed style - backcountry style with wider skis and skins for uphill.

Or climbing steep stairs ( not stair master - bad for knees).

Swordfighting with my favorite sparring partner -- we were very much equals in just about every way, and our bouts could go for hours and range for yards around. Of course, we were both far too stubborn to give up, and if we didn't watch it our muscles would stiffen up so badly the next day we could hardly walk. Ah, the good old days...now she's in the Navy, and I had to sell my blades in order to pay rent.

Racquetball. I was so overweight and out of shape but I LOVED the after workout rush.

My gym offered a class called cardio drill. It was 45 minutes of 6 - 7 intense drills with active recovery between each one. It was so intense I could feel the lactic acid forming in my legs.

Regular strength training probably was one of the hardest thing. I remember doing 20 repetitions of each muscle group every night. These daily activities helped me so much to grow taller.

You would not believe how many times I wanted to give up Ok.

But, I really did it, there and then with the exercises to grow taller ok. There is bench press for the pectorals, curls for the biceps and machines for leg lengthening and strengthening exercises. I would come home with sore muscles and feel much taller and stronger the next day.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
