Typically, if you lift 60%-80% of max, you could do anywhere from 10-20 reps. Lifting at 80% and above takes you down to the lower rep range, which is where you'll be if you're trying to gain size. That means keeping your reps somewhere between 8-16, if you're lifting for weight loss and fitness. Your weights are determined by the number of reps you're doing. Choose a weight you can only lift 16 times. This is hit or miss, so you're experimenting. You don't need to go to complete failure, but make sure you're challenging your body. If you could do more than 16 reps, make a note that you need to increase your weight for next time.
Overall, the physical education curriculum serves the purpose of standardizing the curriculum in a school district across schools and ensuring equitable education for all students. It also results in improved teacher quality and increased consistency in instruction.
Physical education provides opportunities for students to gain current knowledge of physical fitness facts, healthful living practices, leisure time pursuits, stress management techniques, and to receive instruction in the skills necessary for successful participation in activities necessary for optimum health and physical efficiency.
