When doing any weight lifting excercise if you want to gain muscle try a heavier weight and do more reps for example maybe a 30-35lbs and 10-12 reps for 3 sets. If you want lean muscle try 15-25lbs and 15 reps for 3 sets.
try to do each of these exercises 3 times each (3 sets)
and don’t forget to drink your water!!!
Bent Over Low-Pulley Side Lateral (these are definitely a little more challenging, you might want a super lightweight at first, remember you can always substitute in a band or a dumbell..these pictures are just reference)
also, always make sure your back is straight and at an angle, you don’t want to hurt yourself
