Functional & Group Training — all lessons

Equipment used in functional training

An overview of functional training tools — bodyweight, bands, cables, dumbbells, kettlebells, medicine balls, stability tools, sleds, ropes and ladders — and when each is the right choice.

Learning objectives

  • Describe the main functional training tools and their properties
  • Match equipment to training goals
  • Explain the force profiles of free weights, cables and bands
  • Set up equipment safely in group and small spaces

Before this lesson

Why this matters

Equipment shapes the force a client experiences. Knowing each tool’s mechanics lets you choose the right one for the goal rather than the most fashionable.

Tools and their properties

ToolResistance profileBest for
BodyweightGravity on body segmentsFoundations, anywhere training
Elastic bands/tubesIncreases with stretchMatching strength curves, home use, rehab
Cables/pulleysConstant tension, any directionRotational and horizontal work
DumbbellsGravity, independent limbsUnilateral work, stability
KettlebellsOffset centre of massBallistics (swings), carries, get-ups
Medicine ballsCan be thrownPower, rotational throws
Stability balls / BOSUUnstable supportBalance, trunk control (low load)
SledsHorizontal friction, little eccentricAcceleration, conditioning
Battle ropesRapid upper-body workConditioning
Ladders, hurdles, conesSpatial targetsFootwork, coordination

Elastic resistance training produces strength gains similar to conventional weights in a meta-analysis [lopes2019].

Safety

  • Inspect bands for nicks; replace damaged ones.
  • Kettlebell and medicine-ball areas need clear space.
  • Match implement weight to skill; ballistic tools amplify technique errors.

Common mistakes and misconceptions

Case study

A trainer equips a home-visit kit: three bands, two adjustable dumbbells, a 12 kg kettlebell and a 4 kg medicine ball. Every major pattern can be loaded and progressed, and clients improve as well as they did in the gym.

Knowledge check

Knowledge check · 0/5

1. Which tool provides resistance that increases as it is stretched?

Answer B. Band tension rises with elongation.

2. Cables are useful because they…

Answer B. Pulley direction can match horizontal or rotational tasks.

3. Which equipment is most suited to throwing for power?

Answer A. Medicine balls can be released, allowing full acceleration.

4. A sled is particularly useful for…

Answer B. Sled pushes have minimal eccentric component, limiting soreness.

5. A key safety practice in group functional training is…

Answer B. Space and maintenance reduce accidents.

Short-answer & application questions

  1. Choose equipment for a 10-person class in a small room and justify.
  2. Compare the force curve of a band squat with a barbell squat.
  3. List safety checks for bands and kettlebells.

Key takeaways

  • Choose equipment for the training effect, not novelty.
  • Free weights load vertically (gravity); cables provide constant tension in any direction; bands increase tension as they stretch.
  • Implements like kettlebells and medicine balls suit ballistic training.
  • Safety: inspect equipment, manage space and match load to skill.
