Starters guide to cardio workouts

Generally speaking, today there are three forms of cardiovascular training that are prevalent: steady-state cardio (continuous activity for a long duration at a relatively low intensity); high intensity interval-training, or HIIT (high-intensity bursts alternated with
low-intensity “active recovery” or full rest); and metabolic conditioning, or “metcon” (made popular by CrossFit; high-intensity work incorporating all varieties of exercises and rep
schemes and often prescribing no formal rest periods).

So which form of cardio should you be doing? That’s a debate that rages on daily in gyms across the country and on social media and Internet message boards, typically in a rather passionate manner. “Truth is, they all work,” say Grinnell. “It just depends on your goals
at the time as to which way you sway more. As a beginner, it’s beneficial to do all three so your body feels its different energy systems, and you can find what works best for you.”       That said, Grinnell strongly suggests performing the following three cardio/ conditioning sessions each week. These can be done on non-lifting days (Wednesday, Saturday, and Sunday if you lift Monday, Tuesday, Thursday, and Friday); or after lifting sessions
(Cardio Workout 1 in the same session as the Day 1 lifting workout, and so on).                     Note: If you’re performing a cardio workout on an off day, perform the dynamic warmup before the workout.

Ball Slam
Hold a med ball overhead and rise onto your toes. Explosively slam the ball into the
floor, catch it on the rebound, then start the next rep.

From a standing position (1), quickly drop to the floor (2) and perform a pushup,
then pop back onto your toes (3) and finish the rep with a jump (4). Perform all
reps in the set continuously.

1. Cardio Workout 1: High-Intensity Interval Training (HIIT)

Using the treadmill, bike, or rowing ergometer, go at an easy pace for two to five minutes to get a feel for the movement. Then perform eight rounds of 30 seconds as fast as possible followed by 30 seconds of rest. If HIIT is new to you, you can increase your rest intervals to 60 seconds and/or reduce the work interval, moving toward the prescribed 30 on/30 off prescription.

2. Workout 2: Steady State

Perform 20 to 60 minutes of moderate intensity cardio (about 140 to 180 heartbeats
per minute) on a bike, treadmill, elliptical, or other machine or activity of your choice. If you’re deconditioned, start at 20 minutes and add five to 10 minutes each week.

3. Workout 3: Metabolic Conditioning (“Metcon”)

Perform as many reps and rounds of the below circuit as possible in six minutes. Add one minute every two weeks as you improve your conditioning until you reach 10 minutes.
