Hey bud! Well, since you are no stranger to weights, then your body should react quickly to the reintroduction of weights to your fitness regimen. I would definitely map out a weight
lifting program which includes basic movements for all muscle groups, so you can build upon your foundation and then when you do get your body fat even lower, you will have even more to admire and be proud of. Weights, cardio and
clean eating, along with rest will get you to where you want to be!
I would hit the weights asap so you can maintain the muscle you do have, when you are cutting. This is important!
