We have the following formula:
[tex]T=R+\frac{3}{5}(M-R)[/tex]
Where: T = training heart rate
R = resting heart rate
M = maximum heart rate = 189
Then solve for T, given R:
R = 60
[tex]T=60+\frac{3}{5}(189-60)=60+\frac{3}{5}(129)=60+77.4=137.4[/tex]
R = 62
[tex]T=62+\frac{3}{5}(189-62)=62+\frac{3}{5}(127)=62+76.2=138.2[/tex]
R = 64
[tex]T=64+\frac{3}{5}(189-64)=64+\frac{3}{5}(125)=64+75=139[/tex]
R = 68
[tex]T=68+\frac{3}{5}(189-68)=68+\frac{3}{5}(121)=68+72.6=140.6[/tex]
R = 70
[tex]T=70+\frac{3}{5}(189-70)=70+\frac{3}{5}(119)=70+71.4=141.4[/tex]
R = 72
[tex]T=72+\frac{3}{5}(189-72)=72+\frac{3}{5}(117)=72+70.2=142.2[/tex]
