Best forYou want a multi-use weighted ball for tossing, core twists and squats and don't mind older-style workout DVDs

A durable, versatile medicine ball that reviewers rate above the accompanying DVDs, worth it mainly for the ball itself if you can work around dated, fast-paced instructional videos.

Overview

A weighted core-ball workout kit from The Firm, pairing a 5 pound soft medicine ball with a removable 3 pound insert, three workout DVDs covering seven routines, a fitness guide and a 60-day meal plan. Aimed at home exercisers who want a compact strength and cardio system rather than a single piece of equipment.

The ball itself gets more consistent praise than the DVDs. Several reviewers compare its build quality to the pricier UGI Ball, noting it holds up over repeated tosses, squats and oblique twists. The workouts move fast and require some practice before the transitions feel natural, so expect a learning curve in the first few sessions rather than an immediate flow.

  • 5 lb soft medicine ball with 3 lb insert
  • 7 workouts across 3 DVDs
  • Rotational fitness calendar guide
  • 60 day meal and nutrition plan included

What buyers say

From Amazon customer reviews.

Most reviewers rate the ball itself highly for durability and versatility, several comparing it favorably to the pricier UGI Ball. The DVDs draw more mixed feedback: some find the instructor delivery repetitive, and multiple reviewers say a single 15-20 minute workout isn't enough on its own, preferring to combine two per session. One reviewer's low rating was about a shipping delivery issue rather than the product itself.
