How to choose weight

Every person is unique. For this reason, when working out, it's extremely important to maintain proper form. That way you can make sure your muscles are being worked, while keeping your injury risk minimal.

It's not about lifting the most weight. It's about the proper form of execution. How you do each exercise is what really matters. You can lift less weight than another person, but if you're doing correctly, and they aren't, you'll see greater gains than them.
When choosing the weight, we suggest to start with a light weight just to get a feel for the exercise and perform it with proper form. From there, gradually work your way up until you find a weight that challenges you to complete with good form all the suggested number of repetitions. When you find this weight, write it down on SmartGym. 
A weight is too heavy if you struggle to maintain proper form or can't hit the number of repetitions set out in the routine. With a weight that's too heavy, you risk injuring yourself or unintentionally using muscles you don't mean to work to compensate.
A weight is too light if you easily go through all of your repetitions and could even do extra ones. Though you may feel like working out, that doesn't mean the weight is challenging.
You should be able to maintain proper form right up until your last repetition (but not much longer).
