Abstract

An exerciser includes a safety block having two through holes defined through the safety block and two cutouts defined in two opposite sides of the safety block, two elastic strings respectively extending through and securely received the two through holes of the safety block, two safety pads each provided to opposite sides of the safety block to securely connect to one end of the two elastic to allow an operator to work on thigh muscles and two rings connected to a corresponding one of the two safety pads to allow the operator to work on chest muscles.

Claims

1. An exerciser comprising:

a safety block made of rubber and having two through holes defined through the safety block and two cutouts defined in two opposite sides of the safety block;

two elastic strings, each having a first end and a second end, respectively extending through and securely received in a corresponding one of the two through holes of the safety block; and

two safety pads each having a first side and a second side and each provided to opposite sides of the safety block to securely connect to one end of the two elastic strings and each pad having an arcuate recess defined to correspond to one of the cutouts on each side of the safety block to define therebetween a space to allow an operator to work on thigh muscles by recovery force of the two elastic strings when two knees are respectively extended through each of the spaces between the safety blocks and the safety pads.

2. The exerciser as claimed in claim 1, wherein each safety pad has two positioning holes defined to securely receive therein a head which is formed on ends of each of the two elastic strings, each head has a diameter larger than a diameter of the positioning hole so that after the head is received in the positioning holes, engagement between the two elastic strings and the two safety pads is secured.

3. The exerciser as claimed in claim 2, wherein each safety pad further has two paths respectively defined to correspond to one of the two positioning holes to allow the two positioning holes to communicate with ambient air so that the two elastic strings are able to be received in the corresponding positioning holes by sliding through the paths.

4. The exerciser as claimed in claim 1 further having a first ring securely attached to one side of a corresponding one of the two safety pads such that the operator is able to work on muscles on the arms with the recovery force of the two elastic strings by stepping on one of the safety pads and holding the ring.

5. The exerciser as claimed in claim 2 further having a first ring securely attached to one side of a corresponding one of the two safety pads such that the operator is able to work on muscles on the arms with the recovery force of the two elastic strings by stepping on one of the safety pads and holding the ring.

6. The exerciser as claimed in claim 3 further having a first ring securely attached to one side of a corresponding one of the two safety pads such that the operator is able to work on muscles on the arms with the recovery force of the two elastic strings by stepping on one of the safety pads and holding the ring.

7. The exerciser as claimed in claim 4 further having a second ring securely attached to the other side of a corresponding one of the two safety pads such that the operator is able to work on muscles on the chest with the recovery force of the two elastic strings by holding the first and the second rings.

8. The exerciser as claimed in claim 5 further having a second ring securely attached to the other side of a corresponding one of the two safety pads such that the operator is able to work on muscles on the chest with the recovery force of the two elastic strings by holding the first and the second rings.

9. The exerciser as claimed in claim 6 further having a second ring securely attached to the other side of a corresponding one of the two safety pads such that the operator is able to work on muscles on the chest with the recovery force of the two elastic strings by holding the first and the second rings.

10. The exerciser as claimed in claim 7, wherein the safety pad further has screw holes defined to align with securing holes defined in two ends of each of the first ring and the second ring so that a securing element is able to extend into the aligned screw holes and the securing holes to secure engagement between the rings and the safety pads.

11. The exerciser as claimed in claim 8, wherein the safety pad further has screw holes defined to align with securing holes defined in two ends of each of the first ring and the second ring so that a securing element is able to extend into the aligned screw holes and the securing holes to secure engagement between the rings and the safety pads.

12. The exerciser as claimed in claim 9, wherein the safety pad further has screw holes defined to align with securing holes defined in two ends of each of the first ring and the second ring so that a securing element is able to extend into the aligned screw holes and the securing holes to secure engagement between the rings and the safety pads.
