The effects of exercise variation in muscle thickness, maximal strength and motivation in resistance trained men

Randomized Controlled Trial
Human
2019

The study found that switching up exercises using an app helped people feel more motivated to work out, just like the claim says, and they still gained strength just as much as those doing the same routine.

If you're already used to lifting weights, using free weights or machines won't make a noticeable difference in how much stronger you get or how fast you can push the weight after 8 weeks of training.

If you're already trained in lifting weights, whether you use free weights or machines, you'll get about the same strength gains after 8 weeks—as long as you're lifting the same amount, at the same intensity, and moving through the same range of motion.

If you're already strong and lift weights, training each muscle group either once or five times a week for eight weeks will give you about the same strength gains on the bench press, squat, and row.
