Training With Coach

Strength & Performance at Legacy.

Strength and performance training uses progressive overload on the major lifts and athletic movements to build force, power and resilience. It serves anyone who wants to be stronger, from a first barbell squat to a competitive athlete preparing for a season.

01

Technique before load

Lifts are taught and reviewed first, because a clean pattern makes heavier weight safer and more productive.

02

Planned progression

Weights, sets and reps are laid out across weeks, with built-in lighter weeks, so strength climbs without constant plateaus or burnout.

03

Training that supports your sport

For athletes, the program is matched to the demands and calendar of the sport: strength in the off-season, power and maintenance as competition nears.

04

Tracked numbers

Every session is logged, so you can see what you lifted last month and what the next target is.

Who strength & performance coaching suits
  • People who want to get measurably stronger
  • Athletes who need strength and power for their sport
  • Newer lifters who want to learn the main lifts properly
  • Experienced lifters who want an outside set of eyes and a structured plan
A typical first month

Every plan is built around the individual, so your coach will adjust this. As a general shape, the first four weeks of strength & performance coaching tend to run like this.

01

Week 1: Learn the lifts

Squat, hinge, press and pull patterns are taught and assessed with light weight.

02

Week 2: Establish working weights

Sets and reps are set at manageable loads, and you start logging each session.

03

Week 3: Progress

Small weight or rep increases are added where technique allows.

04

Week 4: Lighter week and review

A planned lighter week lets the body adapt. Then your numbers are reviewed and the next block begins.

Common mistakes this coaching fixes
  • Adding weight before technique is solid
  • Training with no plan or log, so progress cannot be seen
  • Skipping recovery and expecting steady gains

The best test is the free introduction: if the plan makes sense to you, you have your answer.

Is strength training safe if I have never lifted?

Yes, when it is coached. A good coach starts with a movement assessment, teaches the patterns with light loads, and progresses only when your technique is solid. Tell your coach about any injuries or medical conditions at your introduction.

How soon will I get stronger?

Most new lifters add weight within the first few weeks because technique and coordination improve quickly. After that, progress follows a plan of gradual loading, rest and consistency.
