Your friend is telling you about their gym session. Help them combine these sentences using a perfect participle clause (Having + past participle).

"After I had completed my workout, I grabbed a smoothie."

Choose the correct rewrite.

The correct answer is Having completed my workout, I grabbed a smoothie.

Replace the time/sequence clause ("After I had…") with a perfect participle clause: Having + past participle. This shows the first action was completed before the second.
