## Questions & Answers

A: No way it'll  look like a Rocket Launcher . Wait till you get where you're going, then buy another Bullworker. Then give it to the puny hellboy

**Q: Does it come with the exercise 🤔 manual, binder version as shown on the picture?**
A: There is a booklet but you dont need all they show in it. Work out a routine that suits you. Do three sets of each. I would incorporate a set of 5kg Dumbbells.  All can be carried out sitting down. Then have a good walk before or after.  If the Weathers bad invest in a Step up bench. You've got your own Gym then. Good luck
