Actually, I don't think that we have too many skinny men. I think we have too many obese men.
Join a gym. They are cheaper than you think. Try to get in there for 60-90 minutes each day. Nowadays, they are equipped with TV screens. Or, you can use a personal device to listen to music or even lectures. The time flies by.
>> I think we have too many......Poodles.

Indoor gyms do have the benefit of providing equipment for isolating specific muscle groups - facilitating injury prevention for actual manly activities.
But my favorite "Gym" routine these days involves about 6 hours a week with shovel and a wheelbarrow.
Shovel, wheel, dump, repeat.
