is thar a way to get stronger without gym equipment?
Well, I've done stuffloads of summer jobs with my dad; he's a general contractor, so I lift heavy things very frequently on the jobsite. If your dad isn't a general contractor however, you don't necessarily have to go to the gym to become stronger. Just eat healthy, exercise at least three times a week for at least a half hour, if not more, and, my personal favorite, push-ups and sit-ups.
Push-ups = increase bicep/pectoral/back strength.
Sit-ups = increase abdominal/back/core strength. For legs, you can do a whole lot; run, hike, bike, climb up and down stairs repeatedly (sounds tedious but it really works).
Oh, and I swim a lot. Swimming is
extremely good strength training, and it's pretty fun, especially if you go with friends.
