  • I spend a grand on a nice adjustable dumbbell set and a bench and went from 165lbs to 210lbs over the last 18 months with a combination of weight training and eating better. It’s absolutely possible to work out at home with the resources that are out there these days. I do miss some of the equipment at the gym but the convenience of a home gym is just too good.

    I would point out that getting lean/shredded is not a function of the gym, it’s a function of the kitchen. You cannot out exercise a bad or even mediocre diet. You can use a gym to build muscle, increase flexibility, or improve cardiovascular fitness, but there’s no avoiding making changes to your diet if you want to decrease body fat.





  • The spring imparts the same amount of energy to the marble and bowling ball. The two objects are not at the same velocity, the marble would be moving significantly faster.

    The same velocity doesn’t necessarily imply the same amount of kinetic energy right?

    Not at all.

    E = 1/2mv^2

    Since energy (E) is provided by the same spring in both cases, the energy of the bowling ball and the marble are equal. Since mass (m) is much higher for the bowling ball, the bowling ball’s velocity (v) must be significantly lower.
