Am I doing enough?
Hi Adrienne. You’re doing great. Just keep doing what you are doing. Mostly the "vary the program" thing is for weight training. Your body becomes accustom to that same exercise, wt and reps within 3 to 6 weeks for beginners. Advance trainers might change things every week. As a general guideline, once you hit a wall and can't add weight or reps to an exercise from week to week, it's probably time to change...something. It doesn't necessarily have to be the exercise that changes. It can be the sets, rest time or reps. Only reasons I can see to vary it with cardio is to beat general boredom, just to do something different. Maybe have more intense or less intense days for recovery or doing different cardio machines so you don't get repetitive motion injuries (doing the same thing over and over can cause wear and tear in one range of motion and not strengthen others). Good luck Earl
