What do you have in mind?
Gain weight?
Lose weight?
Or just to break a sweat?
If you wanna lift weights to gain muscle, you need to know your body type first.
And then the types of workouts for targeted muscle groups.

If you’re thin, focus on big muscle groups such as chest, back and legs.
Do compound exercises rather than isolation.
Create a set of reps for every exercise type.
If you don’t have the strength to complete full 10 reps, it is fine, no big deal.
Try to do something like this instead i.e 4 sets of bench press.
As your increase your weight, you lower your reps.
1x10 reps, 2x8 reps, 3x6 reps, 4x4 reps.
Carefully choose weight you can handle until that last set (4x4 reps).
Focus on the technique and stick to the regimen until you feel that 4x 4 reps is easy later on you know you gain strength.
Don’t forget to take a break after you finish a set i.e 45 seconds. Loosen up and stretch.
And have a rest day to recover those muscles.
