I bought a weight for $11 from 99cent store, because I needed to weight my inflatable kayak which I would use as half way transportation in my trip to the retreat (Tri State Bible Conference, NJ) tomorrow.
Max load of Intex Challenger K2 from ebay (+- $80 value) is 350Lbs.
I weight 215 Lbs.
Based on Hamwi formula, I should weight 143 pounds ideally for 5' 7" height. I need to drop weight to 127-159 Lbs.
Although, I believe with my telescope and all, I will not exceed the load right now.
Never diet. Only excercise.
